Summary
The user is facing an issue with a task that worked in April on flyte-binary version 1.10 but is now failing on version 1.13, likely due to a backend change. They suspect a missing dependency is the cause, as the stacktrace shows a TypeError related to outputting a pandas dataframe, indicating that neither 'pyarrow' nor 'fastparquet' is available for parquet support. The user is advised to install one of these dependencies.
