Experiment stuck on "Initialising the Experiment"

URL of experiment: https://pavlovia.org/arkadiym/oddball_test_76

Description of the problem: This experiment works in Builder, but is stuck on the “Initialising the Experiment” page after I hit the “Pilot” button. It looks like the sync was successful. I also got rid of import statements, recreated the shuffle function in java from scratch, and updated some arrays (initially involving numpy), in order to make this javascript compliant.

@arkadiy, I think this is an issue with closing brackets in one of your arrays - at the beginning of the experiment you have defined a nested array called ISI_Num, but this array is missing a closing square bracket, causing a syntax error.

thank you for catching this!
