Sudden ActiveCampaign Module Error [Function 'isValidResponse' finished with error! Body is missing.]

I need to retrieve a contact from ActiveCampaign to get Custom Fields infomation that will be sent to Sheets and other documents.

Everything worked just fine until a week ago.

Suddenly my ActiveCampaign “List Contacts” module always run an error in every scenario I have it. This is a Core module for all my scenarios and for my company.

What should I do?

Hi Pedro_Oliveira_Mento,

I had the same issue. The issue resolved when I switched the “Include Custom Fields” option to “No”.

Thanks, Peter


I have a “List Contacts” on ActiveCampaign too. They my module stopped working 2 weeks ago with this error “The operation failed with an error. Function ‘isValidResponse’ finished with error! Body is missing.”

I verified my ActiveCampaign connection is works. Not sure why it is getting an error. Please help.

I genuinely apologize for any inconvenience and frustration this situation has caused.
Thank you very much for your understanding and for your patience :pray:


I found a solution!! At least worked for me. On the active campaign module, go to “Status” (if you don’t see this field, go all the way down and select “Show advanced settings” first). On that fields, “Status”, cswitch to “map” and write “Active”.
Save and run the scenario again. That was the fields that was bringing the error.

Use an error handler as an option. So when the error happens it will update the contact, that way you will get the contact id. Then on the next module you can use that id to get the contact.


submitted ticket.
Is there any update?
