What happened?

If "null" is sent to the server and when trying to get data through "Services :: request () -> getVar('myKey')", the error "Argument 2 passed to dot_array_search () must be of the type array..."

Steps to Reproduce

I am sending a POST request without data

Expected Output

Services :: request () -> getVar ('myKey') function should return "null"

Anything else?

File:
system/HTTP/IncomingRequest.php

public function getJsonVar()

Line 540: $data = dot_array_search($index, $this->getJSON(true));

if $this->getJSON(true) returns null then an error appears

Solution:

$getJson = $this->getJSON(true) ?: [];
$data = dot_array_search($index, $getJson);
