Failing to add a galaxy role with a "documentation_url" 404 error from github api

I’m trying to add my first galaxy role

and I’m getting this error:

If anyone bumps into this error:
turns out that ‘documentation_url’ has nothing to do with the ansible meta parameter with the same name, but just a sad coincidence… :frowning:
The issue is really a 404 from github api trying to find the meta/main.yml file in the expected place.
Which turns to be is in the root folder of the repo.

Hope this would help someone else who bumps into this error
