CFE-ConfigValidator-13: Cannot convert value to boolean

This error occurs when MPF expects a boolean value (i.e. true or false) for a config setting but got a value of a different type.

Examples

For instance, the debug setting for a switch is a boolean:

switches:
  s_flipper_left:
    number: 1
    debug: true   # we want all the details about this switch in the logs

You can see which settings are boolean in the config reference of your device.

Common Pitfalls

Widget Animations Repeat

In MPF versions before 0.53 repeat in widgets has been an integer which has been converted to boolean internally. A lot of examples (and the tutorial) contained repeat: -1. You need to change this to repeat: false to fix this error.

Using Quotes

If you use debug: "false" (with quotes around false) MPF will not recognize false as a boolean but as a string. Remove the quotes to fix this.
