carloea2 opened a new issue, #8272: URL: https://github.com/apache/texera/issues/8272
### What happened? Python operators that return an empty list fail while normalizing output. The generic list matcher peeks at the first item and raises `StopIteration`, which becomes `RuntimeError: generator raised StopIteration`. Expected behavior: an empty list produces no output tuples. Before: empty list output raises a runtime error After: empty list output produces no tuples ### How to reproduce? Call `all_output_to_tuple([])` and consume the returned iterator. ### Version or branch 1.3.0-incubating-SNAPSHOT on main ### Commit hash 50321e403c82df299a13deb50a7f9849dd93bdba ### Browsers Not browser specific ### Relevant log output RuntimeError: generator raised StopIteration -- This is an automated message from the Apache Git Service.
