update getObjectProperty(msg,expr) to support invalid expression to return undefined instead of crashing
Quick Check
m = {a:{b:{c:{d:{e:"hello"}}}}};
console.log(getMessageProperty(m,"a.b.c.d"))
console.log(getMessageProperty(m,"a.j.c.d"))
{ e: 'hello' }
undefined
instead of with current code
result = ( typeof obj[key] !== "undefined" ? obj[key] : undefined);
^
TypeError: Cannot read property 'c' of undefined
