Heroku Error R10 (Boot timeout)

[samratjp]

Hey there!

Thanks for making this :)

I tried all the app bootstrap steps on bash but am indefinitely seeing R10 errors -
"-> Web process failed to bind to $PORT within 60 seconds of launch"

For good measure - I tried restarting and it def gets stuck at that step. Any advice?

Cheers!

Having the same issue upon deployment. Details below.

Superset version

Current version

Expected results

After what appears to be a successful deployment, the default app setup should work..

Actual results

After what appears to be a successful deployment, when the app is first loaded, the standard "Application Error" page appears. Here are the corresponding logs:

I had the same issue and tried my own deployment. I adjusted my procfile to "superset runserver -p $PORT" and updated to the most recent version of Python 3.6. It worked just fine after that.
