We are trying to use RESTFUL service to send JSON data to Appian.

The parameter is defined of any type which is a CDT. So, in the expression rule based on 'messageid' shared in request header, the request detail will be sent in response.

= httppostwithresponse(
endpoint: URL(),
paramNames: {},
paramValues: {},
headerNames: { cons!HEADER },
headerValues: {
(
TraceId: "",
SourceIpAddress: "",
SourceHostName: "",
RelayedBy: "",
ApiVersion: "",
SessionId: "",
Originator: "",
UserRole: "",
OperationName: "",
processId: ""
)
},
body: "
{
          ""request"": {
                    ""gtwyReqHdr"": {
           ""TraceId"": ""String"",
""MessageId"": ""MESSAGE"",
""SourceIpAddress"": ""String"",
""SourceHostName"": ""String"",
""SourceTimestamp"": ""YYYY-DD-MM hh:mm:ss"",
""RelayedBy"": ""String"",
""ApiVersion"": ""String"",

                                                  ""EmpID"": "&ri!employee.EmpID&",
                                                  ""Name"": "&ri!employee.Name&",
                                                  ""Role"": "&ri!employee.Role&"

                                                  }
                                        }]
                              }
                    }
          }
}"

)

I am able to get a response when the fields are given hardcoded values within the quotes say “123” or when the rule inputs are individual fields and not a CDT.
When it is a CDT I get the below error –
Expression evaluation error at function 'httppostwithresponse' parameter 6 [line 22]: Invalid index: Cannot index property 'EMPID' of type Text into type Text
