Licenses plugin: unsupported context user

[amedee]

I'm running Metrics as a GitHub Action.

I have one error in rendering, with the Licenses plugin:

Rendering                                                       │

My repos mostly have MIT license and some LGPL.
Some repos are without license.

Am I missing something in my config?

I think I found the answer: the licenses plugin is not compatible with the Classic template according to the Plugin compatibility matrix.
