ActiveCampaign Error List Contacts

In just the past day or so something has changed with either the ActiveCampaign API or how Make is calling it. The List Contacts module returns an error no matter what data I send to it. All my other ActiveCampaign modules work (Create/Update a Contact, Get a Contact, Add a Tag to a Contact).

This error only started happening within the last 2-3 days I believe. I have re-verified my AC connection. I have deleted and recreated my connection. Nothing seems to work.

You can see that the module also shows errors when you attempt to setup a new one.
