Hi, when running a python script node, I get the error seen on the screenshot [image] [image] Same happens with this code too: [image] The script input is output from the csv reader node. How can I get the right name for that table? Best wishes, Dario

@Dalmatino16 maybe you take a look at this simple example on how to handle data in and out of python nodes [image] AttributeError NoneType object has no attribute 'to_arrow_table' KNIME Analytics Platform @sirabelk3 I think you should make sure you have the latest version of the KNIME Python integration installed or a working Python installation of your own . Also you should check what type of data your code would produce. If you want to bring data back from Python to KNIME you would have to have an Arrow data table. Often you would have a Pandas data frame that you would then convert to Arrow. Maybe check out these examples.

input table name? - python script
