Thanks! I’ve removed all plugins from app.yml. I left only the docker\_manager plugin. I also removed all custom css from my theme. I still cannot rebuild.

Since the output of `./launcher rebuild app` is large, I’m copying the latest lines here. I still think that I cannot upgrade because of a theme issue, not sure if CSS related.

I also see this error: `ActiveModel::MissingAttributeError: missing attribute: minimum_discourse_version`
