Why would set not work?

The `Set` also works. And there is no way to tell before each actual use case which one is correct.  
Using `Move` avoids unnecessary duplicates of data. And it is given to user in one step. Comes handy if project grows as you can imagine.  
But I think the cookbook page or `Change` node info can be improved to help users understand benefit of correct usage of those commands.

Meanwhile... the actual error would seem to be the extra . in the property

You need it as per @colin ' s post above `msg.payload[0]["COUNT( DISTINCT uuid)"]`  
if you use the [] syntax you don't use . as well.
