I am receiving this error after trying to deploy to fly.io. I was able to deploy it a month ago with the same project folder. How can I fix this?

I started getting this error as well, this evening, was not getting it a few days ago.
I destroyed app/db and builder, tried to rebuild, but build would hang on
mix phx.gen.release --docker
ran that manually, was able to launch new app.

However after, when I try to deploy I again get the same error reported.

I was able to resolve this issue from

  • destroy app, db, builder
  • remove fly.toml/Dockerfile
  • run mix phx.gen.release --docker --ecto

release was successful and now can execute
flyctl deploy
and it worked. Thanks: kernel panic when deploying app
