Php crud api return empty array on POST

I'm using php crud api so the GET and DELETE working perfectly but not the POST and PUT ?

POST REQUEST

/records/posts/

CONTENT

{
    "title": "Black"
}

return me an empty array :

HTTP/1.1 200 OK
Content-Type: application/json; charset=utf-8
[]

and PUT return me :

HTTP/1.1 422 Unprocessable Entity
Content-Type: application/json; charset=utf-8

{"code":1002,"message":"Argument count mismatch in '1'"}

GET and DELETE are working nicely , any ideas ?
