Describe the bug
I need to be able to set "unknown" or "unavailable" state to the sensor which is of timestamp class.
Unfortunatelly whatever I pass to state of the sensor, HA complains (while NR shows no error)
Here is exemplary flow which NR executes without problem:

And here snippet from HA log in response of executing flow above

I tried to pass null value, 'unavailable' (which btw is reported as Unknown later), and 'unknown' from example above
What is the valid way to set unavailable state to timestamp sensor?
