Using survey in pavlovia experiment results in resource load error

Online experiments Pavlovia Surveys
1

I added a very simple survey as a json file to a working experiment done completely in js in the builder. As soon as I’m trying to test it in the browser, I get this error:

  • unable to download resource: survey.grey_style.css (./lib/vendors/survey.grey_style.css)

Usually I know at least at how to google my problem, but I’m kind of stumped here. I got a different unable to download resource error before, something about a js library, and found a hint online that it might have been fixed in a later version, so I upgraded my psychopy version vom 2024.2.2. to 2025.1. But now this css library doesn’t load.

I just tried to start it from the pavlovia page, and there the survey works. Seems to be about starting it locally in the browser.

Do you have a lib folder in your experiment folder?

3

I do, there is a css, iife.js, iife.js.msp, js, js.LEGAL.txt and js.map file for version 2024.2.2. up to 2025.1.1 in there.

Make sure it hasn’t been uploaded to GitLab. It should be skipped because it should be in the .gitignore file

5

It’s in the gitignore file, and not uploaded to gitlab.

Hi Alexander,

Did you manage to solve the issue? And if yes, could you please share how? I am having exactly the same problem. The survey works well on the Pavlovia page, but I get the same error if I start the experiment including the survey component with the json file locally in the browser.
