Improve operability :
When httprequest fails to perform (like receiving HTTP 500)
We do have proper exception but are missing the current URL details.
This is problematic and slow down investigation when dealing with pipeline doing many distincts httpcall (we often need to reverse engineer the pipeline to understand what was the target of the missed call)
This US is about complementing the exception text along with the current URL.
