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):

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.
(TrustScience) daidoji@worklaptop:~/TrustScience/UCVDCC/w3c_issuer_verifier_api$ docker build -t swagger_server .

It may be due to absent of connexion.apps in the latest (or selected) versions of connexion package. There is a page v2.9.0, but not for v2.7.0. In your log we can see 2.7.0, where it's absent. https://connexion.readthedocs.io/en/2.9.0/autoapi/connexion/apps/ (ok) https://connexion.readthedocs.io/en/2.7.0/autoapi/connexion/apps/ (404 not found)
I had the same issue today, and this is a workaround i used to solve it : Open the "requirements.txt" file which present inside the unzipped folder named "python-flask-server-generated" and update the connexion version to "connexion >= 2.7.0, < 3.0.0" instead of "connexion >= 2.6.0"
