Testdriven.io: Test-Driven Development with FastAPI and Docker Error when running Github Action Test Docker Image

  docker, fastapi, github-actions, python, testdriven.io

I am working through the Testdriven.io: Test-Driven Development with FastAPI and Docker course and am currently on the continuous integration section. In this section you use github actions to build your docker image and run tests and linting and what not.

During the Test Docker Image step of the flow I am receiving the following error when pytest is attempted: Error: Process completed with exit code 137

        run: docker exec fastapi-tdd python -m isort . --check-only

Running pytest against the docker container locally works. There doesn’t appear to be any other logs that I can access that would shed more light onto why this is happening. Any help would be appreciated.
