When i try to optimize my model, I get the following error:

The pyomo model and the logs are included in the zip-file.

Could you send me the Pyomo code for your problem?

Thanks for the fast response. I fixed the issue. For some reason pipenv installed a wrong version of pyomo. I reinstalled the package and it works now :)
