Fly deploy release command failed

Hello,

So I’ve had no problems with deploying to fly.io up until now, where seemingly randomly I’m now having this error whilst trying to update a live site:

Running myapp release_command: /app/bin/migrate

-------
 ✖ release_command failed

Check its logs: here's the last 100 lines below, or run 'fly logs -i e82d61dc769468':

Error: release command failed - aborting deployment. error release_command machine e82d61dc769468 exited with non-zero status of 127

Before this I had a file not found error.

So far I’ve tried:

• Completely deleting the app, builder and database
• Cloned to my linux laptop and tried to deploy - same error except the error status is 1 not 127

I’ve seen a related post or two but none that helped me..

Any insight would be much appreciated. Cheers!
