I have attempted to run the OpenUBA backend Python code, but each time I try to start the server i.e. by running the make command in the Linux terminal, I encounter the following error.

After cloing the OpenUBA repo (https://github.com/GACWR/OpenUBA), I installed the python libraries. When I ran the python backend code, I got the errors as explained above.

Environment:
OS: WSL Ubuntu 22.04.5 LTS
Python version: Python 3.7.17

Issue: Despite following the setup instructions as per the documentation, I keep encountering the above errors. I have not made any modifications to the original code.

Could anyone kindly guide me on how to resolve this issue?
