I have been running a Zap to my ActiveCampaign for the past 4 months and it has been going fine. Suddenly today it started returning this error message. However, the contact id or email is always filled in. Here is what I’m getting.

However, the Zap is set up to pull the email from column Z in my Google sheet.

This column has not changed and emails are still there. How can I get this to work because I need this trigger to update my contact so it will trigger the email automation.
Please help.
