Stuck with errors in the python extension development tutorial

Hi, using Knime 5.3.2, I’m trying to integrate some scripts we have to allow our users to use knime, but getting stuck starting up.

I’m using the tutorial from Create a New Python based KNIME Extension

I was able to successfully launch and run the original but seeing odd errors as I progress which makes me think I have something basic wrong.

When uncommenting the parameters, (tutorial step 10). it warns on start up - “Loading model settings failed: Parameter missing for key “some_param”.” Interestingly, it says this for whatever is the first parameter being loaded, but not the others. Once I click ok it proceeds to run, and I can see the parameters available in the config for my node.

Next going through step 11, it gives an import error when trying to run “to_pandas()” on my input table - “ImportError: DLL load failed while importing _ctypes: The specified module could not be found.”

This is being run from conda environment created clean with the command from earlier in the tutorial… It causes the node execute to fail obviously, which is a hard stop for me.

Anything obvious I might be missing? Thanks!
