2 ModuleNotFoundErrors from newly generated python flask app on editor.swagger.io

Hello. Generated a flask app based off this spec https://w3c-ccg.github.io/vc-http-api/ which I've also attached from editor.swagger.io.

Unzipped and tried to run from the command line and I got

(TrustScience) daidoji@worklaptop:~/TrustScience/UCVDCC/w3c_issuer_verifier_api$ python -m swagger_server
Traceback (most recent call last):
  File "/usr/lib64/python3.9/runpy.py", line 197, in _run_module_as_main

ModuleNotFoundError: No module named 'connexion.apps'; 'connexion' is not a package
(TrustScience) daidoji@worklaptop:~/TrustScience/UCVDCC/w3c_issuer_verifier_api$ pip freeze | grep connexion
connexion==2.7.0

As you can see it can't find connexion but the module is installed.

If I try to run the docker image I get the following ModuleNotFound error for aiohttp.

Start by reproducing both commands, python -m swagger_server and docker run, then inspect the generated swagger_server/encoder.py, swagger_server/__main__.py, and requirements.txt. Trace the reported imports and dependency installation paths; done means the generated Flask app starts successfully both locally and in the Docker image.
