Your post does not say what node.  
Please post a simple flow showing issue, so we can see what is occurring.

I have edited the topic category as this is not about developing a node.

Pure guessing: `msg.payload` isn't an `object`, but coming in e.g. as `string`.  
Insert a `debug` node before the `change` node to verify the `msg` object that is sent.

Well it certainly won't work if you inject a timestamp into the change node, as msg.payload.status will not exist.
