Nginx – App not starting with cryptic Passenger log error

I have a Rails app set up with Passenger + Nginx.
When trying to access the app I get the following error in passenger’s logs:

/home/my_user/.rbenv/versions/3.3.1/bin/ruby: No such file or directory -- Passenger AppPreloader: /home/my_user/domains/my_domain/app/current (LoadError)

However the file /home/my_user/.rbenv/versions/3.3.1/bin/ruby and the directory /home/my_user/domains/my_domain/app/current both exist…

I have tried many things but I’m not even sure how to investigate the issue… any suggestions?

    This is an issue with the Passenger Docker.

    Issue has been raised for the bug: https://github.com/phusion/passenger-docker/issues/409

    As a quick fix which worked for me, you can add below line in your Dockerfile:

    RUN gem install bundler --force -N -v "$(tail -n 1 Gemfile.lock | tr -d '[:blank:]n')" && bundle --version

    After upgrading Alma Linux kernel to 4.18.0-553.8.1.el8_10.x86_64 and deploying an updated Rails 7.1 app, passenger started to return the same No Such File or Directory error. Disabling passenger’s smart spawning error made the problem go away.

    Using passenger 6.0.23
