integration of Appian workflow with DocuSign

Tyler- Interestingly, I creates CDT & tried to work through that my CDT expression looked like:

[status=sent, emailSubject=Request a signature via email example, documents=[documentId=1, name=Test_sign_PDF_Template.pdf, documentBase64=31754], recipients=[signers=[name=Rishu Bansal, email=r.rishubansal@gmail.com, recipientId=1, tabs=[Signer_tab_SignHereTab=[xPosition=25, yPosition=50, documentId=1, pageNumber=3]]]]]

But I still got the same error:

{ "errorCode": "INVALID_REQUEST_BODY", "message": "The request body is missing or improperly formatted. Cannot deserialize the current JSON array (e.g. [1,2,3]) into type 'API_REST.Models.v2.recipients' because the type requires a JSON object (e.g. {\\"name\\":\\"value\\"}) to deserialize correctly.\\r\
To fix this error either change the JSON to a JSON object (e.g. {\\"name\\":\\"value\\"}) or change the deserialized type to an array or a type that implements a collection interface (e.g. ICollection, IList) like List<T> that can be deserialized from a JSON array. JsonArrayAttribute can also be added to the type to force it to deserialize from a JSON array.\\r\
Path 'recipients', line 1, position 1718938."}

Any Idea?
