"circular reference that cannot be persisted" issue in Node Red

[eljarno]

Describe the bug
For several times I get the response of having circular reference that cannot be persisted once I use the state response. I'm using a virtuell temerature sensor getting the information from the Hue Motion Sensor. This worked all the time without any issues. Now I'm flooded by this debug message every 10 seconds. which comes from this specific Red Node.
