REST API - CreateAccount call Failing

[anandshahgrange]

CreateAccount call is failing with the following Provisioning Comments.

{"auditDetails":{"CreateAccount":[{"headers":null,"message":"","statusCode":null,"description":null,"status":"Failed"},{"headers":null,"message":"","statusCode":null,"description":null,"status":"Failed"},{"headers":null,"message":"","statusCode":null,"description":null,"status":"Failed"}]},"CreateAccount":{"headers":null,"message":"","statusCode":null,"description":null,"status":"Failed"}}

Where am I going wrong?

There no object with ${account} in rest connector change it to ${accountsObj?.name}
