Heroku dyno keeps rebooting constantly

问题

I've just deployed a new project to Heroku using Docker.

Unfortunately, my dyno is in a reboot cycle and hasn't come online yet. It continuously crashes with the following logs:

I've tried upgrading the dyno to Hobby, rebooted all dynos multiple times but nothing seems to fix it.

I am indeed listening on process.env.PORT.
