Python Flask deploy failing

1

Hello,

I am trying to port my python flask app from Heroku (where it works)
and although the build is successful, the Deploy is marked as “failed” and the website doesn’t work.

Unfortunately there is no real error message - except the warnings:

Feb 19 05:48:20 PM  WARNING: You are using pip version 22.0.4; however, version 23.0.1 is available.

Anything I am missing? Or how could I get more information?

Thank you!

Those logs don’t seem to show any obvious issues.

Hi Alan

thank you! The service id is com.dibulo.cv.python

Unfortunately I don’t have any more information other than the logs provided. Unless there are other ways to get more detailed logs?

I’m still not seeing anything obviously wrong, but it looks like your app didn’t respond to the healthcheck in time, maybe try a new manual deploy?
