Trying use Azure AD B2C for SSO using generic_oauth and getting vague error when trying to troubleshoot

I don’t understand why you want to use api_url , when refered topic (SSO using Azure AD B2C - #3 by hnnsj ) doesn’t configure api_url.

when I attempt to leave this un-configured I get the following:

EROR[04-22|15:03:24] Error getting email address              logger=oauth.generic_oauth url=/emails error="Get \"/emails\": unsupported protocol scheme \"\""
