$patch remove keyword from required

[mostafahatem20]

I saw in the tests how to add an attribute to the required keyword { "op": "add", "path": "/required/-", "value": "q" }
but I want to ask how can i remove a keyword from being required I tried
{ "op": "remove", "path": "/required/-q"} but it did not work i seem to get it wrong so if anyone can help I would be grateful.
Thank you

Value-based array operations are not supported yet in JSON patch. See this issue: json-patch/json-patch2#18
You need to remove values in an array based on index.

An example target JSON document:

   { "foo": [ "bar", "qux", "baz" ] }

A JSON Patch document:

   [
     { "op": "remove", "path": "/foo/1" }
   ]

The resulting JSON document:

   { "foo": [ "bar", "baz" ] }
