  "message": "fix: ADC with impersonated workforce pools (#877)\n\nWhile service account impersonation is uncommonly used with workforce\r\npool external credentials, there is a bug where the following commands\r\nraise exceptions when impersonated workforce pools are used:\r\n\r\n- `google.auth.default()`\r\n- `google.auth.load_credentials_from_file()`\r\n\r\nThe issue is due to `google.auth.aws.Credentials` not supporting the\r\n`workforce_pool_user_project` argument in the constructor, unlike\r\n`google.auth.identity_pool.Credentials`.\r\n\r\nThis was indirectly passed here:\r\nhttps://github.com/googleapis/google-auth-library-python/blob/a37ff00d7afd6c7aac2d0fab29e05708bbc068be/google/auth/external_account.py#L395\r\nCausing a TypeError to be raised (we only catch ValueError).\r\n\r\nUpdated the credential determination logic to explicitly check the\r\nsubject token type. This is a more reliable indicator instead of a\r\ntry/catch.\r\n\r\nIncreased unit test coverage in tests/test__default.py to cover these\r\ncredentials.",
