Infinite initializing experiment

Hi both @Yura_Markov @jon , I think have the same problem. This is what I got in Stdout:

Alert 4210:JavaScript Syntax Error in ‘Begin JS Experiment’ tab. See ‘Line 1: Unexpected token’ in the ‘Begin JS Experiment’ tab.

8415.2480 ERROR Line 111: Unexpected token in Pri_word.js
8416.0981 ERROR Line 103: Unexpected token in Pri_word-legacy-browsers.js

This is the error line

inicodeClock = new util.Clock();

Below this line are these two lines

import * as random from 'random';
import * as xlrd from 'xlrd';

Do you know how to fix this? thanks a lot!
