Your example is a perfect _ **bug** _ of what it's failing to do! Thank you for your feedback. The problem there is that it's doing a shallow merge; that is to say msg.payload is getting overwritten with a single property each time. Therefore the internal buffer is only containing _msg.payload.first\_name_ _ **or** _ _msg.payload.last\_name_ but not (Schrödinger's cat aside) both at the same time.

Had it been (sans payload) _msg.first\_name_ and _msg.last\_name_ that would have worked.

I've now implemented a **deep merge** routine that should provide the expected results and will now work with your example. Please see node-red-emerge version 1.2.0.

Thank you for your feedback!
