"500 something went wrong on our end" when accessing builds page of a commit

Hi, I'm running a Gitlab CE instance in a docker container with the following volumes:

/mnt/data/gitlab/config:/etc/gitlab
/mnt/data/gitlab/logs:/var/log/gitlab
/mnt/data/gitlab/data:/var/opt/gitlab

I just pulled gitlab/gitlab-ce v8.4 and restarted my container to run the latest Gitlab 8.4 image.

Now when I click on the build status icon of a commit (for instance, /mygroup/myproject/commit/2783897e58de7e38eb09213fe1c02bcc8c384e56/builds), Gitlab throws a 500 error with the following stacktrace:

ActionView::Template::Error (undefined method `artifacts?' for #<GenericCommitStatus:0x00000006be0748>):

I added gitlab_rails['artifacts_enabled'] = false to gitlab.rb and restarted the container but I still get the same error.
