Pabbly connect with Wix to Mailchimp issue

I am getting following response when i want to create a new member selecting Mailchimp app in action on getting webhook repsonse from Wix form.

Your request doesn't appear to be valid JSON:
Parse error on line 1:
"{ \"email_address\"
^
Invalid string, it appears you forgot to terminated the string, or attempted to write a multiline string which is invalid

Seems some backslashes are creating issues. How to fix them ?

Hey @amardeepjaiman

The action step has undergone a few modifications. Please reconnect the action step and attempt the request once more.

I'm hoping this will be useful to you.

its creating a new issue now. When i try to add a new member in mailchimp using the same Action, it says below for new member as well and send 400 error code.

"[email hidden] is already a list member. Use PUT to insert or update list members."

Hey @amardeepjaiman

Since the member was already on the list and you have passed the same member again, so the action step has shown the message for the same.

Use PUT to insert or update list members."

Mover, the action step on the platform is integrated from their API docs only, so we cannot interfere with their functionality.

I hope you would understand.

But that member was new and was not already added to mailchimp audience contact list :(
