Precompile asset esbuild failure does not trigger CI build exit

[Mycobee]

When rails assets:precompile fails in a github actions CI pipeline, the build continues without raising a build error. This caused some broken code to sneak in to our prod instance this morning.

Does anyone have any ideas how to trigger an error where it will stop the CI build? The output below is printed out, but the CI build continues

Example:

doppler run -- bundle exec rails assets:precompile --trace
  shell: /usr/bin/bash -e {0}
  env:
    CI: true
    RAILS_ENV: test

Is it possible this is fixed now, or was an issue with the build script?
I just tried to reproduce this and could not. The assets:precompile task had an exit code of 1 for "bad" JS.
