Hey guys, I’m trying to set up my first zap between LegitFit and MailerLite but I’m getting the following error code from the LegitFit side:

Error code: Error while retrieving: The app returned "Cannot read properties of undefined (reading '_id')".

Can someone please advise on how to rectify and solve this.

Many thanks,
Barry

Hi ​@barryd_coach,

 

Welcome to the Community.

We acknowledge the error in the integration between LegitFit and MailerLite, where the Zap is trying to access a missing '_id' field. To resolve this, users should verify the trigger setup, review data fields, and ensure LegitFit sends the correct information. Testing with sample data can help identify inconsistencies. If issues persist, contacting LegitFit is recommended for further troubleshooting.
