ExtendScript encoder.encodeSequence

Okay - I have no idea why but fiddling around with VS Code solved the problem.

Now I don't get an error message but nothing gets added to the Media Encoder queue (it launches just fine)

code :

var project = app.project;
var sequence = project.activeSequence;
var outputFile = "/Users/Me/Desktop/EncoderTest/test.mp4";
var encoderPreset = "/Users/Me/Documents/Adobe/Adobe%20Media%20Encoder/15.0/Presets/PeersPreset.epr";

app.encoder.launchEncoder();

app.encoder.encodeSequence(sequence, outputFile, encoderPreset, 0, true);
