RESTlet to Add / Update Customer

I am attempting to create a RESTlet that will receive a JSON data payload and will create a customer record. When testing my RESTlet I receive the following error message:

 {"error" : {"code" : "JS_EXCEPTION", "message" : "You cannot save this record without providing both Default Shipping Address and a Default Billing Address."}} 

Below is my RESTlet code:

 function add_createRecord(datain) {   var fieldname;   var recordID;   var updateID;   var record;   var err;   var value;   var status;      if(!datain.recordtype) {    err.status = "failed";    err.message = "payload recordtype missing";    return err;   } else if ((datain.status == 'update') && (!datain.recordid)) {    err.status = "failed";    err.message = "payload set to update, missing record id";    return err;   }      status = datain.status;      if(status == 'create') {    record = nlapiCreateRecord(datain.recordtype,'dynamic');        for(fieldname in datain) {     if(datain.hasOwnProperty(fieldname)) {          if((fieldname != 'recordtype') || (fieldname != 'status') || (fieldname != 'recordid')) {       if(fieldname != 'address') {        value = datain[fieldname];        if(value && typeof value != 'object') {         record.setFieldValue(fieldname, value);        }       }
