Pavlovia, "TypeError: event in undefined"

Description of the problem:

Hello everyone,

I’ve just started to put together my very first experiment. I have (very) limited knowledge about Python and Psychopy, therefore I am testing everything step-by-step before moving forward to the next chunk of my code/ experiment.
So far, I have a greeting screen with a very direct instruction (“press space”), followed by a screen where two lines appear: on the upper line, a cross is moving “automatically”, whereas, on the lower line, the user can move her cursor (on a given coordinate).
This is so far what I wanted to achieve and to test, I uploaded it to Pavlovia (exported as HTML, then synched my work).
The problem comes when I try to run (in Pilot mode) my experiment: after the first screen (“press space”), I can see the following error message: TypeError: event in undefined
The script works well in PsychoPy. May I ask your opinion on what the problem might be?

I am linking my experiment (see above), it is as spaghetti as it could be.

Thanks for your help in advance!

Sounds like you need event=psychoJS.eventManager; in code_JS as described in my crib sheet (see pinned post).

Try this solution for hiding the mouse cursor. If it works for you, I’ll add it to my crib sheet.

I don’t believe it’s changed in PsychoPy, but I think you might be able to make a code component that will do it. Try adding this javascript code to the beginning of the routine where you want to hide it, or if that doesn’t work, on each frame in that routine: document.body.style.cursor='none'; You may need to add the following code in the next routine to un-hide it: document.body.style.cursor='auto';
