How to understand the HTTPRequest Error Object reference required
I am trying to call to a website that renders a xml structure as a response.if I put the url on the browser an xml rendered page is returned but if i call to this using the below code I get an object reference error which I am finding had to understand is there anyone who could help understand this error or point me in the right direction thanks.
Set tSC=$$$OK
Set httpRequest = ##class(%Net.HttpRequest).%New()Set httpRequest.Server = "msedgewebdriverstorage.blob.core.windows.net"
Set httpRequest.Port=443
Set httpRequest.ContentType ="application/octet-stream"
;;"application/xml"
Set httpRequest.SSLConfiguration="Open"
Set httpRequest.Https=1
Do httpRequest.Get("/edgewebdriver"_$C(63)_"comp=list")
Do $System.OBJ.Dump(httpRequest.HttpResponse)
please note the SSL is just an empty SSL configuration to be able to use https

I have no idea, from which error you talk.
ClassMethod MyRequest()
{
set req = ##class(%Net.HttpRequest).%New()
set req.Server = "msedgewebdriverstorage.blob.core.windows.net"set req.SSLConfiguration="Open"set req.Https=1do req.Get("/edgewebdriver/?comp=list")
set rsp=req.HttpResponse
if rsp.StatusCode=200 {
write"Data Size: ",rsp.Data.Size,!
write"Dumping the first 256 bytes..."zzdump rsp.Data.Read(256)
} else {
write"Return Code: ",rsp.StatusCode,!
write"Resp.Phrase: ",rsp.ReasonPhrase,!
}
quit rsp
}The output is just fine... no errors.
do##class(...).MyRequest() --->

You have to work with the Data property of the response object (which is a 1.8MB stream)
Having tested this outside a restricted environment I realised my problem was the proxy server as the htttpResponse was not being instantiated, the work around was to use the proxy sever and running everything through the proxy tunnel.
ClassMethod MyReq()
{
set tSC=$$$OK
set req = ##class(%Net.HttpRequest).%New()
set req.Server = "msedgewebdriverstorage.blob.core.windows.net"
set req.ProxyPort=**
set req.ProxyServer="*******"
set req.ProxyHTTPS=1
set req.ProxyTunnel=1
set req.SSLConfiguration="Open"do:tSC req.Get("/edgewebdriver/?comp=list") Do $System.OBJ.Dump(req.HttpResponse)
quit tSC
}
