attempted relative import with no known parent package on Google AppEngine with Python3.7

Question

Getting the following error:

"/srv/server.py", line 12, in from .routes.solver import route as solve ImportError: attempted relative import with no known parent package

Deploying the app to AppEngine Standard env, and my project looks like so:

---/
 |_app.yaml
 |_server.py
 |_routes
   |_solver.py

In server I do from .routes.solver import route as solve and get the above error in GCP, but not locally.

I tried https://stackoverflow.com/a/16985066/483616 and a few others. Tried with __init__.py at pretty much every level and every location. Then saw that it wasn't needed for python3, so removed. Pretty much unsure what to do now.

Tried this too https://stackoverflow.com/questions/2354166/how-do-you-modify-sys-path-in-google-app-engine-python. Both /srv and /srv/routes were on the path before using import. Did it with append and insert(0 — knownasilya, Apr 28 '20 at 15:46
Added back `__init__.py` too, since the official v3 docs mention it. — knownasilya, Apr 28 '20 at 15:51

Not optimistic that this is the answer but just to throw it into the pot, have you seen Problem with Python relative paths when deploying to Google App Engine Flexible ?

Thanks. Yeah that looks like the same issue, but also no answer there. – knownasilya Apr 29 '20 at 14:26
