Troubleshooting MailChimp 'Invalid Resource' error when subscribing users from Zoom

Question

Trigger: User registers for a webinar on Zoom
Action 1: Subscribe user to List #1 on MailChimp
Action 2: Subscribe user to List #2 on MailChimp

Most of the zap runs have worked fine. But for one zap run, we got this error message on Action 2:

The outgoing data doesn’t include any IP information. Also, MailChimp was accepted Action 1. Any idea what could be going on?
