Why I can't use type 'any' for the slot phone_number

hi there, i just used ‘any’ type for the slot phone number, but it’s throw error,

InvalidSlotConfigError: An AnySlot cannot be featurized. Please use a different slot type for slot 'phone_number' instead. If you need to featurize a data type which is not supported out of the box, implement a custom slot type by subclassing 'Slot'. See the documentation for more information: https://rasa.com/docs/rasa/domain#slots

but i read the docs, but it’s saying we can use ‘any’ type as well!

here is my phone_number slot

    type: any
    influence_conversation: true
    - type: from_entity
      entity: phone_number

Change influence_conversation: false.

I recommend setting all slots to influence_conversation: false by default and try to avoid featurized slots.
