python - Google: google.auth.exceptions.RefreshError: ('invalid_grant: Bad Request', '{\n "error": "invalid_grant",\n "error_description": "Bad Request"\n}')

Question

オンラインでGoogleシートを読み取る小さなpythonボットを実行し、ユーザーからプロンプトが表示されたときにその情報を不和にサーバーに送信しますが、1〜2か月間使用されておらず、現在は機能していません。そのため、Google認証サービスへの呼び出しでエラーをスローして認証資格情報を更新しているようで、何を試すべきかについてのアイデアがありません。完全なエラーと、それが壊れている完全なコード セクションを含めました。
