msg.originalPayload issue when input is a buffer #7

Open Steve-Mcl opened 3 years ago

Steve-Mcl commented 3 years ago

msg.originalPayload (when input is a buffer) is just a reference so if the data is byteswapped, originalBuffer is affected.

Consider cloning before processing.

Consider making the extra properties optional (to cleanup the msg)

Probably you can do all that in a function node, force a cloning for an internal structure will slow all execution to solve a particular use case
