[info] does `/app/bin/migrate` exist and is it executable?

Hi all,

Been deploying for quite a while now and last night too. Nothing changed, but now seeing this:

 2023-07-03T11:03:29.890 app[9080e475b21278] lhr [info] INFO Preparing to run: `/app/bin/migrate` as nobody

2023-07-03T11:03:29.891 app[9080e475b21278] lhr [info] ERROR Error: failed to spawn command: /app/bin/migrate: No such file or directory (os error 2)

2023-07-03T11:03:29.892 app[9080e475b21278] lhr [info] does `/app/bin/migrate` exist and is it executable? 

Here’s my app and relevant files:

Thanks.

Interestingly all I did was add in this to the [env] section to break it. It’s working again if I remove it:

  # Ecto Pg connection pool size
  POOL_SIZE = "20"

Why would this cause above?

Moving like this is now working. Maybe a blip on fly side or comments not liked?

[env]
  GIT_REV = "a6737a9"
  PHX_HOST = "sentrypeer.com"
  PORT = "8080"
  POOL_SIZE = "20"
