The bugs found in the test seem to have nothing to do with ApplicationCustomScopes.

I don't think this issue is related to the current PR, and it seems there is something wrong with this CI error itself. I checked the token_test.go test file:

	// Delete the object
	_, err = DeleteToken(token)
	if err != nil {
		t.Fatalf("Failed to delete object: %v", err)
	}

	// Validate the deletion
	deletedToken, err := GetToken(name)
	if err != nil || deletedToken != nil {
		t.Fatalf("Failed to delete object, it's still retrievable")
	}

and printed the error message: err.Error() = The token: admin/Token_489387 does not exist.

Looking at the test code, it deletes a token and then attempts to retrieve it. Casdoor correctly returns the error token xxx does not exist, and this error response itself is valid. It seems we need to adjust this test code instead.
