---------------------------------
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.
