OAuth callback has no query string

Error message

OAuth callback has no query string

What it means

In handle_oauth_callback_request: the incoming OAuth callback request's URL has no query component, so required parameters (code, state, error) cannot be extracted. Indicates a malformed or manually-truncated callback request.
