ComputeError in motif discovery

[Ge0rges]

Hello,

I wanted to report this error when running motif discovery.

Traceback (most recent call last):

polars.exceptions.ComputeError: ComputeError: The output type of the 'apply' function cannot be determined.
The function was never called because 'skip_nulls=True' and all values are null.
Consider setting 'skip_nulls=False' or setting the 'return_dtype'.

Can you provide the freeze of the enviroment you are using (pip freeze or conda list if using conda)? And possibly the output in motif.tsv in the nanomotif output folder?

Thank you!
