Hello all, we are having some difficulty with their Power Automate integrations.
Using the Update envelope prefill tabs' action, throws an error:
Action 'Update_envelope_prefill_tabs' failed: The request body is missing or improperly formatted. No tabs specified.
These settings 
produce output parameters such as 
{"accountId": "*****************redacted***********************",
"envelopeId": "****Redacted***",
"documentId": "1",
"body": p
{
"tabType": "text",
"tabId": "00bdf6ac-6c0d-48d4-a819-6cb1ce9485da",
"value": "TestName"
},
{
"tabType": "text",
"tabId": "e2ae030b-7e2f-446b-a2ff-f8e3cc83e394",
"value": "TestAddress"
}
]
}
which returns a HTTP 400 with a body of
{
"errorCode": "INVALID_REQUEST_BODY",
"message": "The request body is missing or improperly formatted. No tabs specified."
}
However if I run a similar query with Docusign's API Explorer, I get what appears to be a successful response
so I assume I am doing something wrong with the Power Automate action parameters, but cannot work out what.
Any help that might point me in the right direction would be appreciated. Thanks.
