JBuilder 2.11.3: uninitialized constant ActionView::AbstractRenderer on load under Nginx/Passsenger

[scott-bergen-talogy]

App environment:

• Ruby 3.0.2
• Rails 6.1.4.1
• Phusion Passenger 6.0.12

Debugging the app in Rubymine works fine but on our servers, the app won't start with the error below. Have not had a chance to troubleshoot yet but it is happening at the Bundler.require step of loading application.rb

App 21999 output: Error: The application encountered the following error: uninitialized constant ActionView::AbstractRenderer App 21999 output: Did you mean?

I can confirm that I have this issue too. In my specs I get this error:

Failure/Error: require File.expand_path("../config/environment", __dir__)

NameError:

I don't believe it's related to nginx/passenger, I'm getting it without.

I thought it was related to Rails 7, I started getting it when I tried running my tests under Rails 7. But you report Rails 6.1.

But the ActionView::AbstractRenderer still exists even in Rails 7...

Aha, I bet it's a zeitwerk loading issue. I bet those having the problem are using zeitwerk; which was optional before Rails 7, but mandatory in Rails 7.

The class is ActionView::AbstractRenderer, but it's located at path action_view/renderer/abstract_renderer.rb -- the extra /renderer in there may be making zeitwerk fail to load it where it did before.

I would like to try to file a ticket in Rails, but I can't figure out how to make a simple reproduction. :( I

am pretty sure this is zeitwerk related though.

Zeitwerk doesn't load the framework code, so this has nothing to do with Zeitwerk. The issue was caused by https://github.com/rails/jbuilder/commit/d84c37d8981e5165275ecd4884c56ab34cd4a65e. I'm fixing.
