Dynamics Table - unable to pass dynamic table Json data via power automate

Hi, 

I am using the “Update document generation form fields from enevlop (Preview)” Demo Connector for Docusign

While forming the input fields for “Sender Fields” and “Dynamics Table”. I am passing the value to the above action in below format - 

The Sender Fields are mapping correctly in the document but the dynamic table sis giving below error:

   "docGenErrors": �

        {

          "tagIdentifier": "{{t:\"TableRow\", e:\"xxxx_xxxxList\"}}",

          "errorCode": "InvalidJsonataEvaluation",

          "message": "Invalid JSONata evaluation. -- Array expected but received String type from this expression: \"xxxx_xxxxList\""

        }
