I am trying to execute the "LogonAndReturnCookie" web api.
I thought everything was configured correctly, but I get the message (401 - unauthorized) :
"Error processing External Provider Sign In information. Custom Scopes from the Request do not match the ones configured."
How do you configure this custom scope in the app / in azure AD / in postman ?
This is the sort of configuration issue that you might want to bring up with Support. There are quite a few moving parts. I see you're pointing to localhost, I don't even know if that would ever work - azure app authentication is not built for that sort of scenario.
