We have defined "https://hoge/callback" as the OAuth 2.0 Redirect URI, but when we actually use it, we specify the user ID in the query parameter. (e.g., "https://hoge/callback?user_id=1")

When I removed the query parameter and used it for a trial, no error occurred.

Has the OAuth 2.0 Redirect URI specification changed?
The problem began to occur on 5/19.
