Hi everyone! I'm trying to automate the calculation of some product systems in the Jupyter Notebook while for some product systems in my Mac, there's an error in Jupyter:
ERROR:root:calculation failed: -32000: Unhandled server error: null
The log in OpenLCA is as follows:

Does anyone know what the problem is and how to solve it? Thanks in advance for any help:)
