I am almost finished with programming this study, but am having an issue with the study not saving data and not completing.

At the end when the study completes I get this error:

 ![image](https://us1.discourse-cdn.com/flex002/uploads/psychopy/original/3X/4/5/45924acc53b5fe7c0b3d2d60a31adf3cca5a439b.png)

I am not sure if I am missing something?

Not a solution I’m afraid, but @hellenjingyuan appears to be having the same issue.

Can you help with this one @jon ?

I am not sure if this is an issue, but it seems that my export html is importing from the old version?

IE it is currently importing this

> import { PsychoJS } from ‘[https://pavlovia.org/lib/core-3.2.js](https://pavlovia.org/lib/core-3.2.js)’;  
> import \* as core from ‘[https://pavlovia.org/lib/core-3.2.js](https://pavlovia.org/lib/core-3.2.js)’;  
> import { TrialHandler } from ‘[https://pavlovia.org/lib/data-3.2.js](https://pavlovia.org/lib/data-3.2.js)’;  
> import { Scheduler } from ‘[https://pavlovia.org/lib/util-3.2.js](https://pavlovia.org/lib/util-3.2.js)’;  
> import \* as util from ‘[https://pavlovia.org/lib/util-3.2.js](https://pavlovia.org/lib/util-3.2.js)’;  
> import \* as visual from ‘[https://pavlovia.org/lib/visual-3.2.js](https://pavlovia.org/lib/visual-3.2.js)’;  
> import { Sound } from ‘[https://pavlovia.org/lib/sound-3.2.js](https://pavlovia.org/lib/sound-3.2.js)’;

but I think it is actually suppose to be this:

import { PsychoJS } from ‘./lib/core-2020.1.js’;  
import \* as core from ‘./lib/core-2020.1.js’;  
import { TrialHandler } from ‘./lib/data-2020.1.js’;  
import { Scheduler } from ‘./lib/util-2020.1.js’;  
import \* as util from ‘./lib/util-2020.1.js’;  
import \* as visual from ‘./lib/visual-2020.1.js’;  
import \* as sound from ‘./lib/sound-2020.1.js’;

I might be off, but not sure.

Also here is url to my study (sorry it has a lot of trials, you might just spam 1 and space through it all)

Still can’t seem to get it to work.

Hey, I removed some of the crib sheet code in the beginning,

> win=psychoJS.window;  
> Array.prototype.append = .push  
> event=psychoJS.eventManager;  
> Object.prototype.upper = “”.toUpperCase;

These were all removed, I am not sure which one was the culprit. Everything works now though!

It should be String.prototype.upper
