I have an app that works great in local and on Heroku
I am trying to deploy my Rails app to fly.io that uses docker, but it fails
I managed to get the logs, but it's had to understand which part is failing:

I am not sure if the error comes from from bin/rails:6, but I got this in the file
#!/usr/bin/env ruby
load File.expand_path("spring", __dir__)
APP_PATH = File.expand_path('../config/application', __dir__)
require_relative "../config/boot"
require "rails/commands"
I thought that it might be bootsnap and I disabled it in production, but it didn't change the error
