Hi All - I'm trying to run the example table UDF example from https://nightlies.apache.org/flink/flink-docs-release-1.16/docs/dev/python/table/udfs/python_udfs/#table-functions. I get an error:
Copy code
org.apache.flink.table.api.TableException: This calc has no useful projection and no filter. It should be removed by CalcRemoveRule.

@Richard Noble Could you share the code snippets which could reproduce this issue?

Sure, will do. I'll put together an image today if I get the chance for each of reproduction
