[NEST Users] Error installing extension module

I would like to install a custom neuron model in NEST so I followed the instructions for the nest-extension-module. It is able to build the .so files but it errors during the final install of the project as seen in the below message. Install the project... -- Install configuration: "" -- Installing: /home/bs/git_repos/extension/nest-simulator/result/include/piftestmodule/pif_psc_alpha.h -- Installing: /home/bs/git_repos/extension/nest-simulator/result/lib/nest/piftestmodule.so -- Installing: /home/bs/git_repos/extension/nest-simulator/result/lib/nest/libpiftestmodule.so Traceback (most recent call last): File "<string>", line 1, in <module> File "/home/bs/git_repos/extension/nest-simulator/result/lib/python3.8/site-packages/nest/__init__.py", line 444 err = AttributeError(f"Cannot set attribute '{attr}' on module 'nest'") I am trying to install one of the example neurons provided first (pif_psc_alpha) so I do not expect that it is an issue within the source files. Thanks for any advice in correcting this issue!
