getScreenshot() returns empty Object

[ender02]

All other functions are working like Click, Swipe, etc. But getScreenshot() not.
This code

var img = getScreenshot();
console.log(img);

Returns:
[object Object]

I work with visual studio code. But I also tried running the script in the Robotmon App, same empty result. I tried with Nox as emulator, on 2 real phones with Android 6.0 and also latest android versions. Same problem everywhere.

What can be the problem? Any idea guys? Do I miss something?

It might not be empty, [object Object] is pointing to a memory address.

Try this

var img = getScreenshot();
var colors = getImageColor(img, 0, 0);
releaseImage(img);
console.log(JSON.stringify(colors));
