'Permission Denied' error when running math service on Linode server

[TechnoGecko]

So I've built the Polis container on a server, and all the services seem to run fine except for the math service. When it gets to this Dockerfile, which has CMD ["./bin/run"] at the bottom, the terminal outputs:

polis-dev-math-1         | /usr/local/bin/entrypoint: line 21: /app/bin/run: Permission denied
polis-dev-math-1 exited with code 126

Is this a pathing issue maybe? I'm running the command sudo docker compose up --build from the server as the root user, so I'm confused as to why I'd be running into permission problems. Any ideas/help would be greatly appreciated, and I can provide more info if needed. Thank you

I'm moving this over to a technical issue, since this shouldn't be happening: #1684.

Will close now to keep discussion over there.
