Overhangio/openedx-mfe:20.0.0-indigo?

I’m trying to reverse engineer how the default tutor k8s deployer does things and I have many things working. I am a bit stuck on getting indigo/custom themes on the mfes. On the main site it’s fine. I naively thought just using overhangio/openedx-mfe:20.0.0-indigo would be enough.

I suspect it’s because I’m getting:

env.config.jsx:240 env.config.jsx failed to apply:  Error: Cannot find module '@openedx/frontend-plugin-framework'
    at env.config.jsx:94:56
    at async a (env.config.jsx:94:28)

In the console (which I don’t get when installing into my cluster with tutor directly).

I tried to site.themes.create(theme_dir_name='indigo') on the site apps.local.openedx.io but it doesn’t seem to do anything.

Any pointers most appreciated.
