#Error Handling

Trying to check date in DTL. 

Want to throw a custom error not the default one from the $ZDTH. It does in the try as will write "Error" when testing the DTL but the actual error not showing. Report errors is turned on.  I also tried the THROW logic from best practices but that doesn't work either. $SYSTEM.Status.DisplayError(status) does display what the error should be returned. 

Hi Community, 
In this article, we will explore the concepts of Dynamic SQL and Embedded SQL within the context of InterSystems IRIS, provide practical examples, and examine their differences to help you understand how to leverage them in your applications.

We are trying to mark a hl7 nack as "completed" to ignore an error and not generate the alert. 

We can remove from adding a managed alert or add another router in 

When Nack of CR of 

Date of birth in PID.7 must not be empty

We tried via this but i think it's only for an actual IRIS alert errror not the HL7 error code/description 

E*Date of birth in PID.7 must not be empty=C,:?CR=C,:?R=RF,:?E=S,:~=S,:?A=C,:*=S,:I?=W,:T?=C

I am looking for a way to capture Data Quality issues with the Source data that is populating HealthShare Provider Directory. 1 way is to use Managed Alerts, but since it could be multiple Providers and different messages it seems silly to alert on every message that has the error. Instead, I was thinking of using the Workflow Engine so it could populate a Worklist for someone to review and work.

Looking over the Demo.Workflow Engine example, I am not comprehending on how to send a task to the Workflow manager to populate the worklist from a DTL.

Hello,

I'm trying to get the Reply Action Code to work with the error message text.

I have this ACK:

MSH|^~\&|APP|FACIL|||20250821143621||ACK|CUEACK_20250821143621|P|2.4
MSA|AE||Failed to queue message

This is some of the Action Codes I've tried:

• E*Failed to queue message=S
• E*Failed=S
• E*"Failed to queue message"=S
• :E*Failed to queue message=S
• :?E*Failed to queue message=S

It's not suspending the message however.

What am I doing wrong?

Thank you

Let's start with a simple motivating question: over the past 14 days, what are my most common errors in the Application Error Log?

Answering this through the management portal or terminal is an annoying manual process - we should just be able to use SQL. Fortunately, there are a few class queries to help with this in the SYS.ApplicationError class in the %SYS namespace. You can answer the question for a single date with something like:

select"Error message",count(*)
from SYS.ApplicationError_ErrorList('CCR','12/16/2024')
groupby"Error message"orderby2desc

Hello Community
I was running code in the terminal and attempted to interrupt its execution. During that process, I encountered an application error with a log entry dated 01/06/1841, the date seems unusual.

Error <INTERRUPT>ErrST+6^%ETN occurred within %ETN itself. Detailed information cannot be logged.

I like the Application Error Log functionality a lot. However, it becomes time consuming to inspect it date by date and directory by directory on a multidirectory server. Ideally, I would use an existing error class to write a custom error report by date, selected namespaces, etc. Does such a system class actually exist? Not that I found. The detail level on the screenshot below is enough.  
Some Application Error Logs go back a couple of years and load for a long while. Is there any programmatic way to clean them? Deleting errors in GUI date by date and directory by directory is rather

Hi,

While HL7 Errors ACKs come back in the soap response, the HL7v2 Error ACK message is not processed. 

I used the SOAP Wizard to construct my classes, but the generated code doesn't handle the HL7v2 ACK.
Does health Connect have a class that handles this?

Failing an official solution should I go ahead and make make my own classes based on EnsLib.HL7.Operation.TCPOperation, but wrapping it with the generated SOAP handling code.

How have others dealt with this?

The Good Old Days

The %Library.DynamicObject class has been in IRIS since before it became IRIS. If you have been using it since the Cache days, you may want to brush up on some of its changes.

In Cache 2018, the %Get method only had one argument. It was the key to retrieving from the JSON, meaning that if your JSON object called myObj, it would look like the following:

Introduction

In this article, exceptions are covered.

Working with Exceptions

Instead of returning a %Status response, you can raise and throw an Exception. You are then responsible for catching the exception and validating it. IRIS provides five main classes to handle exceptions effectively. Additionally, you can create custom exception class definition based on your needs.

You may encounter errors during any point of program execution, and there are several ways to raise and handle these exceptions. In this article, we'll explore how exceptions are handled efficiently in IRIS.

One of the most commonly used return types is %Status, which is used by methods to indicate success or failure. Let's begin by discussing %Status values.

Working with %Status

Hi experts, please, do you know cause this errors in cconsole?
I'd like know what can I investigate.

I am developing a business operation that receives a request, creates a message with the data contained in it and sends it to an outlook email. For testing purposes both the sender and the destination are the same email account
This is the code:
ClassBO.AlertEmailSenderExtendsEns.BusinessOperation{

Hello,

I'm trying to carry a custom error from one business process to another.

BPL:LookupClass fails it's lookup and a custom error of "Lookup XYZ" is generated.

The class quits with that error, but upon quitting, the custom error gets wrapped in an Ensemble System error: 

ERROR <Ens>ErrBPTerminated: Terminating BP LookupClass # due to error: Lookup XYZ

This means, when I use the %LastError property to get the error message, it's not got the value I want to use. In this case, "Lookup XYZ". It instead has "Terminating BP LookupClass # due to error: Lookup XYZ"

Many programming languages use the try-and-catch construct to handle runtime errors gracefully. If the code within the try block encounters an error, it will throw an exception to the catch block, where the error handling occurs. Today we will dive into the ObjectScript implementation of this construct and discuss some ways to clean things up.

ObjectScript Implementation Basics

To get started, we will first look at the basic structure of the try/catch block:

try{
    //some code here
}
catch ex{
    //some error handling here
}

I'm scraping my way through some code that's been around for a while, and came across the use of $ZTRAP and (dear GOD) GOTO for trapping and handling errors.

In an effort to "modernize" it and make it, I don't know, less M-ish (sorry old-timers!), I'm replacing it with Try/Catch blocks.

Some questions:

1. Is this a dumb idea?
2. Anything I should look out for?
3. Did I hurt anyone's feelings?

And if the answer to number 3 is Yes, my deepest apologies ... I love you guys! 🤩

Hi, I am trying to optimize a method, I am only occasionally receiving Internal Server Error from GUI interaction and when viewing the Application Error Log in IRISHealth this is what I see. <UNDEFINED>%0Ac+3^%sqlcq.QM.uEgYAnxQ4duxnAiaOpZgvilz1tlo.1 *sqldata15d : CSP Error .

I have no idea how to read this and pinpoint the issue.

Full details below.

Hello Everyone,

The Certification Team of InterSystems Learning Services is developing an InterSystems ObjectScript Specialist certification exam, and we are reaching out to our community for feedback that will help us evaluate and establish the contents of this exam.  Please note that this is one of two exams being developed to replace our InterSystems IRIS Core Solutions Developer exam. You can find more details about our InterSystems IRIS Developer Professional exam here.

I came up with a challenge for myself to come up with a way to make a variable watch itself for a certain value and do something when it hits that value without having to check it every time something touches it. Basically, a way to say "if at any point during the execution of this code, if x = 0 (or whatever the condition is) do this thing." The class I ended up with watches a %Status:

If you have system tables implementing the "VERSIONPROPERTY" functionality, you may encounter error 5800. This article explains how this error occurs and provides solutions to resolve the issue.

When version checking is implemented, the property specified by VERSIONPROPERTY is automatically incremented each time an instance of the class is updated (either by objects or SQL).

For example:

Hi Community,

I am trying to read a JSON file and convert into HL7 message.Please find the example below

Set Jsonobj={"Doctype":"ADT^A01","PatientId":"123","PatientName":"Alex"}

Set Dynjsonobj=##class(%Library.DynamicObject).%FromJSON(Jsonobj)

Error :<THROW>%FromJSON+37^%Library.DynamicAbstractObject.1 *%Exception.General READ error while reading input stream 10 Line 1 Offset 0

I am getting this error while reading the file,Can you please tell me where i am doing wrong in converting the file?

Work Queue Manager (WQM) is a feature of InterSystems IRIS that enables you to improve performance by distributing work to multiple concurrent processes programmatically. The idea is that you split the work into chunks, and WQM distributes the chunks across worker processes and can provide the info that the work is done.

However, recently, I got an interesting question: there's a large logical transaction composed of ~1,000,000 individual objects and SQL inserts and updates. Some updates are CPU-intensive, so the original idea was to use WQM to split an update into chunks to speed things up. 

Hi All,

When resending HL7 messages out, the receiving system rejects the message indicating the "Message Control ID already exists" (see error below). Iris retries resending the same message until the receiving system crashes and the BO disconnects in Iris. I would like to suspend the message when Iris receives that error and move on to the next message. Is this possible? Can it be handled by the BO Reply Code Actions settings? What reply code actions should I use? 

The error comes back when using the default Reply Code Actions ':?R=RF,:?E=S,:~=S,:?A=C,:*=S,:I?=W,:T?=C'

Hello Community,.

I've updated the IRIS community form 2023.2 to 2023.3 and I didn't see the User defined(Sample) error messages in ^IRIS.Msg global even I verified in both pointer and data level. I re run the set x=##class(%MessageDictionary).Import("error.xml") After import I could see the pointers and data in ^IRIS.Msg

Is the User defined error will reset from the server after IRIS upgrade?

Hi InterSystems Community

We recently had an issue where we weren't able to parse a JSON HTTP request, but the issue went by unnoticed. We also did not have a trace of what the raw HTTP request was that we couldn't parse. I'm looking at improving our this by:

I have been trying to do a backup from tape using the D ^DBREST command.  I am not able to connect to the tape drive, that recently got replaced.  It is configured and I can see it with IBM's ITDT.  I did a test and it came back with the error below:

Are there any suggestions on how to fix this or what commands to use to get this opened and connected?  I do appreciate it.
