I am getting the result that there is a problem, see return message below.

I am using this code within server side in iobroker (node.js).

This is my code. I would be so happy if anybody could help me?

var fetch = require('node-fetch');
const FormData = require('form-data');

doDetection();
function doDetection() {
    request.get({url: "http://192.168.178.124/kennzeichen.png", 
        encoding: null},  async function (err, response, body) {
        if (err) {
            throw err;
        }

        var formData = new FormData();
        formData.append('image', body);

        const response2 = await fetch('http://192.168.178.124:32168/v1/vision/custom/licence-plates',         
            {method: 'POST', body: formData});
        const result = await response2.json();
        log("Result: " + JSON.stringify(result))
    });
}
