Thanks @avinashjoshi 👍

Hi @excid3 it looks like this was merged after the latest release (1.0.1 on November 12, 2024), and I'm running into the issue.
I figured I'd mention it, in case this slipped your mind over the holidays.

In the meantime, I can work around the issue by pointing my Gemfile to the main branch here. 👍

Edit: v1.0.2 was just released to prevent self-referrals & also includes this fix 🙌
