Rebuilding a fresh Discourse install pre-Ember 5 (targeting the beta channel), I am presented with an endless loading screen

Installation

See title. I am in a bit of a pickle now. I am trying to roll back to a pre-Ember 5 build of Discourse to maintain legacy long term service support for my forum, which relies on plugins that have now been rendered inoperable under the new Discourse release. To roll back the clock by a few days, I have cleared everything away (destroyed the container and blew away /var/discourse and repulled from GitHub) and I am starting afresh with a pristine Discourse installation. In my .yml, I have specified “version: beta” so I should be pre-Ember 5.

After I do the usual of setting up my admin account and verifying it, I am presented with an endless loading screen. And yes, I also go into safe mode view and enable Force HTTPS as I always do with my setup.

I have even tried every which way, removing plugins, and even starting afresh with no plugins except the absolute minimum of just…

      - git clone https://github.com/discourse/docker_manager.git

… in my .yml file. No dice. After setting up my admin account, I am still (barebones pristine install) presented with an endless loading screen of death.

Looking at the console, this is what I am seeing currently:

run:
  - exec: echo "Beginning of custom commands"
  ## If you want to set the 'From' email address for your first registration, uncomment and change:
  ## After getting the first signup email, re-comment the line. It only needs to run once.
  #- exec: rails r "SiteSetting.notification_email='info@unconfigured.discourse.org'"
  - exec: echo "End of custom commands"

EDIT: Oddly enough, if I disable plugins in safe mode, the site works. However, if I leave them enabled, it does not. My only plugin is Docker Manager, so why is it failing to load?

This works: https://forum.tabletpc.review/?safe_mode=no_plugins

This does not work: https://forum.tabletpc.review/?safe_mode=no_themes

Right, except right now, I have a clean install with literally nothing on it and the site refuses to load. See the .yml. No plugins. Also, no themes. No theme components. I am setting up from square one and getting the infinite loading screen. No plugins except the Docker Manager. I’m extremely confused why this is not working.

OK, yes, sorry, that is confusing!

So I think you should probably forget beta and switch to tests-passed to see if you can recover a build, then build it back piece by piece.

Indeed. I am going to try doing a fresh install in another environment. It seems beta is broken at the moment. In the past, I could target beta in my .yml. I am guessing that there is a breaking change in the Docker Manager plugin that is not backwards compatible.

That did it. There must be a breaking change in Docker Manager that breaks beta. (Therefore, a warning to anyone on beta as their main container target to not upgrade!)

I’m whittling through and I think I have a good idea which plugin is culprit for mainline / tests-passed.

Verdict: For those like me hanging on to it, with Ember 5, Retort is now dead. :frowning: Looking into options to preserve its features.
