BUG: Throws error "Can't set the temperature because the printer is not ready."

Octoprint.log shows the following error:

2024-01-28 16:12:27,184 - octoprint.plugin - ERROR - Error while calling plugin preheat
Traceback (most recent call last):

octoprint_preheat.PreheatError: Can't set the temperature because the printer is not ready.

While the error is seemingly harmless, it would be nice to catch this excpetion in the code rather than throwing an ugly python error in the log

Any progress on this????
