@rideam , Is there something off with the permissions in the ritza repository. I pulled it down but cannot see the branch this was created on. Also one of the checks have failed. Please verify and let me know if I am doing something wrong tying to access the branch.

Hi @mark-robustelli - we don't have any special permissions on our public fork of your repo. I ran

git clone https://github.com/ritza-co/fusionauth-site
cd fusionauth-site
git checkout draft/migrating-from-rails-to-fusionauth

in a new directory to test and everything seemed to work as expected. Could you let me know what commands you're running and what you're seeing?

The check won't pass until the dependencies mentioned in the description have been merged into your org, as the remote code looks for those in the location that they will be after the merge.

I tried again this morning and seems to be OK. I was getting:
astro (main): git checkout draft/migrating-from-rails-to-fusionauth
error: pathspec 'draft/migrating-from-rails-to-fusionauth' did not match any file(s) known to git

Very odd, but all appears well and will get on this now. Thanks.
