> I was thinking about more high-level test. Like running `SELECT python_udf(CASE WHEN x THEN y ELSE z END)` You may not understand what I mean. What kind of case is not important. You can think that the case you wrote in 1.12 is supported. But in 1.13, we introduced a new rule to support the case of `table.map`. The reason for this error has nothing to do with your judgment statement as a parameter. The reason for the error is because we called the wrong tool method when judging whether to use python udf. `PythonUtil.isNonPythonCall` and `!PythonUtil.isPythonCall` are not mutually exclusive conditions -- This is an automated message from the Apache Git Service.
