Error failed to fetch an image or build from source: executing lifecycle: failed with status code: 46

Hi! Huge fan of fly.io; I’ve migrated my Foundations of Software Engineering class off of Heroku and on to fly and it’s been great minus the occasional fraud alerts (most of my students are far from home and I imagine their billing info looks a bit suspect. :slight_smile: ).

One of my student teams is consistently hitting this issue with remote-only deploys via the GitHub action; I can reproduce it using flyctl locally as well.

Doing a fly deploy with my local Docker instead works fine so it seems that maybe this builder is in a weird state? Not sure how to debug. Results follow:

❯ fly deploy --remote-only

Can you post your fly.toml? This may be a consequence of our newer builders pruning build caches.

Meanwhile, destroying the builder app with fly apps destroy appname should give you a fresh one that may temporarily solve the problem.

Sure, thanks!

This builder image is 2 years old. Can you try with cloudfoundry/cnb:latest? If it still happens there, it would mean a bug in lifecycle that needs reporting.
