Hi @freebluek, maybe the [knime log](https://docs.knime.com/latest/python_installation_guide/#knime-log) or the log console within the Script editor shows in which line exactly that error occurs? It is most likely due to some missing conversion functionality in KNIME. We are [aware of it](https://forum.knime.com/t/bug-unsupported-operand-for-knimepandasextensionarray/64789/3), but cannot say when we get to it. I added this thread in the corresponding ticket. As mentioned in the above link, you might need to do a explicit conversion to … pandas? I have no idea what you are doing 😉 See [here](https://forum.knime.com/t/date-scaffolding-join-dates-with-less-than-greater-than-function/69096/5) for an example. Can you tweak your code like the example and tell me whether it helps? If not, please have a close look at the aforementioned knime log and the console within the script editor and provide them as well as a minimal example to reproduce the issue 🙂 Thanks and best regards Steffen --- _[View the full topic](https://forum.knime.com/t/error-knimepandasextensionarray-cannot-be-created-from-factorized-yet/74278)._
