Error called get request

Hi, I'm trying to send a GET request with Net.HTTP.request to http://dummy.restapiexample.com/ , actually I'm calling this endpoint: http://dummy.restapiexample.com/api/v1/employee/7052

No matter what I try I always get this error:

NotAllowedError: Security settings prevent access to this property or method.

It's a js which is being called at document level, improved security is disabled and I've also tried enabling it.

the code is -->

//<Document-Level>

//<ACRO_source>Init</ACRO_source>

//<ACRO_script>

/**** pertenece a: Document-Level:Init ****/

myTrustedFunction = app.trustedFunction(

    function()

    {

        this.getField("textAJAX").display = display.hidden;

        console.println("2 - ");

        Net.HTTP.request({

            cVerb: 'GET',

            cURL: 'http://dummy.restapiexample.com/api/v1/employee/7052',

            oHandler: {

                response: function(msg, uri, err) {

                    if (err != undefined) {

                        app.alert(msg)

                    } else {

                        console.println("1");

                        var stream = msg;

                        console.println(stream);

                    };

                }

            }

        });

    }

);

//</ACRO_script>
