PUT methods in Azure Functions suddenly are asking for Bearer Authorization.
Endpoints returns HTTP status 401 with a WWW-Authenticate header and its value set to Bearer. If any JWT token is provided, the error changes to:
error="invalid_token", error_description="The signature key was not found"
][1]
No Authorization configuration was set and functions are in anonymous authentication mode.
No code was published before, it was working until last thursday.
GET, POST and PATCH verbs are working.
