Hello everyone, I am currently developing my Pavlovia task, which is a multi-level image recognition experiment (link: https://run.pavlovia.org/Pasteur/sced_experiment/ ). I am encountering the following issue: when loading my resources (there are quite a lot of them), I receive this type of error …

I just tried and got through all the files in the initial download. Do all participants see all items? I’m wondering whether you experienced a network or memory glitch. Perhaps you could try downloading individual files during the iti. [image] Wakefield's Daily Tips Blog …

Most of the time the resources download correctly, but sometimes I get an error — and what’s confusing is that the file reported in the error changes each time.

That’s why I think it might be due to the number and total load, rather than any individual files.

Ahh okay i will check this and I will tell you thank a lot

So in my case the name will be image, imag_2 ect…?

Those are your component names. Are you also using “image” as a variable name within the image_3 component?

Yes I changed it and the errors didn’t occurs yet. I will see if it continues to work when I testing it .

I changed it and ran some tests. I don’t have any issues with it now, but I didn’t notice any difference in the loading system. If I ask Pavlovia to download the file in the background, am I supposed to be able to start the experiment without loading all the files first? Is that possible? Because re…

To prevent the files being downloaded at the start you might need to “hide” the spreadsheet. For example, instead of your loop pointing to conditions.xlsx it could point to $conditionsFile and then you could put conditionsFile = 'conditions.xlsx' in a Begin Experiment tab of a code component.
