Suggested Fixes

  • Ensure that the type of the property set in the property's schema definition is equal to array or object.
  • If the property type is not expected to be an array/object, change the value of the style property to one that supports primitive types e.g. form.
  • If the property type is not expected to be an array/object and you are unsure about which style to use, simply remove the style property definition.
