[jira] [Created] (FLINK-29681) Python side-output operator not generated in some cases

Juntao Hu created FLINK-29681:
---------------------------------

             Summary: Python side-output operator not generated in some cases
                 Key: FLINK-29681
                 URL: https://issues.apache.org/jira/browse/FLINK-29681
             Project: Flink
          Issue Type: Bug
          Components: API / Python
    Affects Versions: 1.16.0, 1.17.0
            Reporter: Juntao Hu
             Fix For: 1.16.0, 1.17.0


If a SideOutputDataStream is used in `execute_and_collect`, `from_data_stream`, `create_temporary_view`, the side-outputing operator will not be properly configured, since we rely on the bottom-up scan of transformations while there's no solid transformation after the SideOutputTransformation in these cases. Thus, an error, "tuple object has no attribute get_fields_by_names", will be raised.
