Error when using EU Advanced Signature with Templates - docusignapi

Question

I'm getting an error when finishing a DocuSign Ceremony using EU Advanced Signature with Templates. The odd thing is that it was working before and still working for ceremonies that have an embedded PDF.
When finishing a ceremony the following error is popping up:
The envelope history shows more details:
It mentions the userEmail, so I've double-checked the JSON and everything seems to be fine, after all, I didn't get any error when creating the envelope.
Here's the JSON using a Template that is failing:

}
Am I missing something? Have anyone ever seen this error before?
It's worth to mention that I'm getting the error right in the first signature (InPerson).
Kind regards

Answer 1

It turned out that is a known issue of DocuSign.

Answer 2

There is a known issue during an in-person signing session when the signer clicks on Finished, he should get the following popup
If you don’t set any email, it will fail with the CONSTRAINT_VALIDATION_ERROR
The workaround is to specify an email.
