@rwalworth Is there something I should do to fix it?

Hey @freya-docs! Nothing more is needed from your side, GitHub is experiencing outages at the moment, so I may have to try running the workflows a couple times before they pass. I'll be sure to merge when it does. Thanks again for your contribution!
