 The rest_invalid_json error was introduced in #38547 which is meant to
 detect defect json in body. However, if a empty body is used, this is
 marked as invalid as well.

 There are scenarios where empty body are used especially when deleting an
 item.

 For example calling a DELETE method on a custom endpoint like the below
 means deleting the ID 1 from the item resource. There is no need to pass
 in any unnecessary body content.

 {{{
 DELETE /wp-json/custom-endppint/item/1
 }}}
