Unable to download resource: .sid: {}

OS: Win11
PsychoPy version: v2024.2.4
Standard Standalone Installation?: y
URL of experiment: Pavlovia
Do you want it to also run locally? (y/n) y

What are you trying to achieve?:
I want this to work on Pavlovia as well as locally. Yesterday it worked fine on Pavlovia, today it does not. I didn’t make any real changes to the experiment, but don’t remember exactly what changed - probably just moving some files (I tried putting copies back where they were). But it says “unable to download resource: .sid: {}”

What did you try to make it work?:

I followed all the advice at the below link. All linked filenames were copied and pasted from the files themselves, so there is no opportunity for case issues. I tried it in chrome and firefox. I tried restarting the machine. I tried making a new folder and a new pavlovia project, then pushing all files. No joy.

Link to the most relevant existing thread you have found:

What specifically went wrong when you tried that?:

Error

Unfortunately we encountered the following error:

when downloading resources for experiment: JasonGuidedUnguided
unable to download resource: .sid: {}

Try to run the experiment again. If the error persists, contact the experiment designer.

I think the issue was I hadn’t linked to an online pavlovia survey. Doh. Solved now.
