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 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=1 do 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.

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.
