when using a Change/Set function on a certain message I get the error mentioned in the title.
I am using Node Red in Siemens Mindsphere environment.
The object is looking like this:
The change function was taken from the palette. I used the debug "copy path" function to pick the values path and use it in the change function with the set operation -- sio, I followed pretty much the user guide.
Is it possible that a message with a different format is arriving at that Change node? Do you still have a Debug node alongside the Change node so you can verify exactly what is being passed into it when you see the error?
The debug node is directly connected to the "read aggregates" node. The payload at the debug node is what I posted in my initial post.
The error is created from the change node.
At the change node output the payload remains unchanged -- so it is exactly what the "read aggregates" node delivers.
