python source systematic error whatever the inside code.

Something has changed in the Knime configuration software somewhere, somehow. Each time I’m trying to use a Python source, I receive the message : ERROR Python Source 0:5 Execute failed: EndVector() takes 1 positional argument but 2 were given. Happens with all python nodes in fact. Hint : when you are inside the node and you use “Execute Script” it works. The bug happens only when you close the node to use it the common way.

So it would try and recreate your Python environment with conda (Miniconda and conda-forge might be a good combination). Maybe we could gain some more insights.
