There weren’t any changes to dockerfile in project. How it could be fixed?

Based on the Dockerfile reference, you can specify a port in one of two ways:

ENV <key> <value>
ENV <key>=<value> …
Because you have spaces around =, Docker thinks you’re using the first form where your key is PORT and your value is = 8000 (which is not a number and probably why Cloud Run isn’t working).

To fix it, either specify the port without spaces (ENV PORT=8000) or without an equals sign (ENV PORT 8000).

This looks like an internal bug. I’m an engineer on our App Platform team and have filed a ticket to track this internally. In the mean time I recommend triggering a rebuild by using the “Deploy” button in the top right.
