Hello all,

I’ve ran into a situation with OpenProject 4.0.8, when I try to add the openproject-costs plugin. I’m hoping that someone can point me in the right direction.

Gemfile.plugins:

Tasks: TOP => db:migrate => environment

Digging through the forums, I found a similar problem here: [[https://community.openproject.org/topics/3378]]
On the advice of that thread, I tried changing the branch from “stable” to “v4.0.1” (I tried it both with “v4.0.1” and “v4.0.8” achieving the same results). That enabled me to complete the db:migrate/db:seed/assets:precompile successfully. However when I restarted OpenProject, it died with these errors;
