Bug: cannot find dynamic plugin

Describe the bug

Get this error on starting up the RHDH container. Is it because the plugin is not disabled by default? See https://github.com/janus-idp/backstage-showcase/blob/3ebd07469048b42322bceedf9f0e7cd15080ed3a/dynamic-plugins.default.yaml#L496-L497

Expected Behavior

What are the steps to reproduce this bug?

1. Start the latest RHDH container via the Helm chart

Versions of software used and environment

1.0-178

Is it because the plugin is not disabled by default?

No, it's not. This seems to be a very recent regression. Could you share the precise helm chart version + container image tag (or even better sha) ?

@nickboldt Do you think it could be related to the change made to install python globally ?

@nickboldt Do you think it could be related to the change made to install python globally ?

I don't think so since I had it working, and the roadie utils plugin being correctly installed, with the following last configuration (from here and the following container image: quay.io/rhdh/rhdh-hub-rhel9:1.0-185

Here's the script I used: https://github.com/joshgav/janus-on-openshift/tree/main/deploy

I just started trying this yesterday from limited documentation and reading code so perhaps there are changes needed to the configuration.

I got past this error, turns out I was setting the runAsUser to 1001 manually in my values.yaml file - I removed that and this error at least has been resolved.

In fact I now see the dynamic package loading :smile:, here's the log line:
