 * With wp_debug set to true we are receiving the following php error on the front
   end of our website when logged in.
 * `rest_validate_value_from_schema was called incorrectly. The "type" schema keyword
   for can only be one of the built-in types: array, object, string, number, integer,
   boolean, and null. Please see "Debugging in WordPress" for more information. (
   This message was added in version 5.5.0.)`
 * Can this be resolved?
