Unknown config object 'heater'

Hey! Hope you are doing well! Noticed you pushed some updates 9 days ago and decided to update Klipper. Update process was without incident. However, when I try to control the printer, this shows up in /tmp/klippy.log:

   self.try_load_module(config, section_config.get_name())
  File "/home/pi/klipper/klippy/klippy.py", line 118, in try_load_module
    self.objects[section] = init_func(config.getsection(section))
  File "/home/pi/klipper/klippy/extras/probe_temp.py", line 268, in load_config
    return ProbeTemp(config)
  File "/home/pi/klipper/klippy/extras/probe_temp.py", line 53, in __init__
    self.sensor = self.printer.lookup_object('heater').setup_sensor(config)
  File "/home/pi/klipper/klippy/klippy.py", line 85, in lookup_object
    raise self.config_error("Unknown config object '%s'" % (name,))
Error: Unknown config object 'heater'

Here's my printer.cfg:

My best guess is that I don't have a specific heater section, but I'm not familiar with the internals of Klipper enough (yet).

Please advise. And THANK YOU for doing what you do!
