How to BUG fix picture naming study

Hello everyone,


Today, I uploaded my picture naming experiment designed in OpenSesame onto the JATOS server. A check run failed multiple times on multiple devices, browsers etc. However, in OpenSesame, everything works perfectly and the experiment is JATOS compatible. How can I find and fix the bug that makes my experiment stop? In the browser, a screen appears: "Oops, something went wrong", and in the output file I cannot find any reported bugs.


Looking forward to hearing from you :)

  • Hi Pia,

    You can try to open the Developer tools (on Chrome: View -> Developer -> Developer tools) and see if you see any errors in the console. We'll then be able to tell if it's a problem with JATOS or OSWeb

    And maybe @lvanderlinden might be able to help from the OSWeb side?

  • Hi Elisa,

    Thank you for responding so fast! This is the coding that appears after refreshing the screen after the bug as the developer tool suggest doing.

    I made screenshots during the experiment:


    Seems like something can't load properly, but again: it works perfectly for a few loops and the all of a sudden an error occurs.

  • This error is typically occurs in web browsers when you click on a link that has an unsupported or unknown URL scheme. The URL scheme is the part of a URL that identifies the type of resource being requested, such as "http://" for web pages or "mailto:" for email links. For ex: You may get this "ERR_UNKNOWN_URL_SCHEME error" during mailto: or tel: links inside an iframe.

    To solve it, try to add target="_blank" in your URL Scheme/Code.

    <a href="mailto:my@email.com" target="_blank">link text</a>

    This error "ERR_UNKNOWN_URL_SCHEME" has no any specific solution till now. Android user and PC user all are facing this error which needs to be sought out. There's a long-standing bug in Chromium regarding how links without protocols are handled. It occasionally is patched, but seems to keep resurfacing. In some cases, prefixing your links with http:// (or https://) should resolve the issue for you.

    Here are some steps you can take to try to solve the "ERR_UNKNOWN_URL_SCHEME" error:

    • Double-check the URL to make sure it is correct and includes the appropriate scheme. If you are clicking on a link, try copying and pasting the URL into the browser's address bar instead.
    • Some browser extensions can interfere with URL schemes. Try disabling any extensions you have installed and see if the error goes away.
    • If the error persists, try using a different web browser to see if the issue is specific to your current browser.
