HACS: Repostitory structure for 2021.7.3 is not compliant

Configuration

I’m trying to install this custom repo

So, I go to HACS > Integrations > Custom Repositories > enter the above URL in the top field, put integrations for the bottom bit, and i get the error below, i also tried loveace, same error. In-fact, this has happened to every singe custom repo I try to install, I haven’t successfully installed a custom repo yet.

Anyone know what my issue is? All the repo’s I try are for Home Assistant but why can’t I install them?
Thanks in advanced for any help.

That’s not a custom component, that’s the latest development version of a core integration.

How do I add core integrations?

They are included when you install Home Assistant. I don’t understand what you want to do.
