title: CFE-ConfigValidator-12: Item is not a dict

CFE-ConfigValidator-12: Item is not a dict

This error occurs when MPF expects a dictionary in a config setting but found something else.

Examples

For instance, show_tokens in a show_player has to be a dictionary:

show_player:
  some_event:
    your_show_name:
      show_tokens:
        dict_key1: "dict_value1"
        dict_key2: "dict_value2"

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

Common Pitfalls

Using a List instead of a Dict

This is a list in yaml:

your_setting:
  - item1_in_list
  - item2_in_list

This is a dictionary:

your_setting:
  key1_in_dict: value1_in_dict
  key2_in_dict: value2_in_dict

This is a list of dictionaries (used in shows for example):

your_setting:
  - key1_in_dict_in_list1: value1_in_dict_in_list1
  - key1_in_dict_in_list2: value1_in_dict_in_list2
    key2_in_dict_in_list2: value2_in_dict_in_list2

Incorrect Indent

With nested configs (i.e. show_player, slide_player or widget_player) you might have used an option which should be indented one level further or one level less. This can sometimes be a bit tricky. Using an IDE with the MPF language server can help here.
