Help with preprocessor script -- Wait until bed is cooled to a certain temperature

[giganteamistoso]

I am trying to program some automation using Continuous Print, and I'm finding it difficult to get a preprocessor script to function that accomplishes what I'm looking for.

I have my bed clearing script set to run on Print Success, but I want a preprocessor to wait until my bed has reached a certain temperature.

The default "If the bed temp...." script only checks the bed temp at runtime, and then since the bed is still too warm, my bed clearing script does not run.

I tried a loop, but this ends up hanging Octoprint requiring a hard restart:

while True:
if current['bed_temp'] < 32:
return True

I couldn't find documentation on how to add a sleep delay, so it's getting stuck in an infinite loop.
