CFE-ConfigValidator-9: Required setting is missing from section in your config

This error occurs when MPF does not find a required setting in one of your config sections.

Examples

For instance, every switch has to have a number in MPF:

switches:
  s_ball_switch1:
    number: 1
This example is tested to be valid MPF config. However, it is not integration tested.
switches:
  s_ball_switch1:
    number: 1

You can see which settings are required in the config reference of your device. For this instance, check the switch config reference and you will find that only number is a required setting.

Common Pitfalls

Omitting one of the required settings

If you omit on of the required settings you will see this error. To this this browse to the config reference of your device and add all the required settings. Alternatively, you could use your IDE with the MPF language server to auto-complete all required settings.
