I'm attempting to upgrade an existing project to the new Python 3 AppEngine Standard Environment. I'm able to deploy my application code, however the app is crashing because it can not find dependencies that are defined in the requirements.txt file. The app file structure looks likes this:
|____requirements.txt
|____dispatch.yaml
|____dashboard
| |____dashboard.yaml
| |____static
| | |____gen
| | | |____favicon.ico
| | | |____fonts
| | | | |____MaterialIcons-Regular.012cf6a1.woff
| | | |____app.js
| | |____img
| | | |____avatar-06.png
| | | |____avatar-07.png
| | | |____avatar-05.png
| | | |____avatar-04.png
| |____templates
| | |____gen
| | | |____index.html
| |____main.py
| |____.gcloudignore
|____.gcloudignore
And the requirements.txt file looks like this:
Flask==0.12.2
pyjwt==1.6.1
flask-cors==3.0.3
requests==2.19.1
google-auth==1.5.1
pillow==5.3.0
grpcio-tools==1.16.1
google-cloud-storage==1.13.0
google-cloud-firestore==0.30.0
requests-toolbelt==0.8.0
Werkzeug<0.13.0,>=0.12.0
firestore-model>=0.0.2
After deploying, when I visit the site on the web, I get a 502. The GCP Console Error Reporting service indicates the error is thrown from a line in main.py where it attempts to import one of the above dependencies: ModuleNotFoundError: No module named 'google'
I've tried moving the requirements.txt into the dashboard folder and get the same result.

A few things could be going wrong. Make sure that:
requirements.txt file is in the same directory as your main.py file.gcloudignore is not ignoring your requirements.txt filerequirements.txt and main.py
