Hi there,
I’m encountering with the following error when trying to deploy my App:
Error failed to fetch an image or build from source: error building: executor failed running [/bin/sh -c SECRET_KEY_BASE=DUMMY ./bin/rails assets:precompile]: exit code: 1
I removed my dockerfile and fly.toml and delete the App in fly.io. Then I re-launched, but couldn’t solve this problem.
Here’s my Dockerfile:
# syntax = docker/dockerfile:1

ARG RUBY_VERSION=3.1.2

Here’s my fly.toml file:

Do you know what should I check to solve this issue?
Thank you very much!
