I'm trying to make an http request, with the UserInfo.getSessionID()
, in the authorization
value, to
https://{{INSTANCE}}.salesforce.com/services/data/v43/ui-api/record-ui/{{sObjectID}}
and It replies the following.
System.CalloutException: Unable to tunnel through proxy.
Proxy returns "HTTP/1.0 404 Not Found"
What I'm trying to do, is to make some REST calls, to the same instance, because of some objects I can't get access with Apex.
How could I do this? I tried doing it like this article, but it uses some urls for the callbacks, and I couldn't got it to work when I adapted the example to my instance.
Is this maybe because of a feature I need to activate for my sandbox? (I'm working in a sandbox)
