I'm sending the request from Twilio, and all of the other fields work other than MailingPostalCode. Any ideas?

       let contact= {
                           FirstName: event.FirstName,
                            LastName: event.LastName,
                            MailingPostalCode: event.ZipCode,
                            npe01__HomeEmail__c: event.Email,
                            npe01__Preferred_Email__c: 'Personal',
                        };

I'm querying for my message's body text. Example - 'Hi my name '+testName+' how are you' 

That string is a text field on the message object. What do I need to do in the code to make those variables work? This string needs to be queried from the object, not hardcoded in the code.
