Are you able to run the sample script I provided from my previous post in the CAD/GUI's script file editor window with the Python API integration set to use the Python bundled by Lumerical 2022 R2.1? This should confirm if you have the API integration working on our machine. 

Which version of CentOS 8? Ensure that you are running on a supported platform and and setup the Python API integration and environment and have read/write access to the "/tmp" folder
