OAUTH_UNSUPPORTED_RESPONSE_TYPE

Issue

The identity provider does not support the response type used in the authorization request. Glean uses response_type=code for the standard authorization code flow, and the provider has rejected it.

Resolution

1. In the identity provider's admin console, verify that the OAuth app is configured to support the code response type for the authorization code flow.
2. Confirm that the authorization URL in the Glean Admin Console matches the provider's documentation.
