How did you got this error? Do you get this error while trying to integrate your form with MailChimp?
I did check your only form in your account and found that it is not integrated with MailChimp yet. Please check the screenshot below:
I created a simple demo form and integrated it with my MailChimp account and it seems to work as expected. Upon sending a test submission, the email address was added in the "Lists".
I would suggest you to integrate your from with MailChimp again and get back to us if the issue persist.
We will wait for your response.
