Can't run experiment on OpenSesame anymore

Hi, I'm having troubles running my experiment in OpenSesame on Windows 10 win32. I've updated it to the most recent version 3.3.9. Also I'm using Python 3.7.6.

Everytime I try to run the experiment, the error: pyglet.gl.lib.GLException: b'Der Vorgang ist ung\xfcltig.' shows up (meaning that the process is invalid). Funny thing is, the error message just startet popping up all of a sudden, in the beginning it used to run without any problems.

I'd be thankful for any help, as I don't have any idea how to fix this!!

  • Hi @Ari422 ,

    This error is related to OpenGL, which is the library that is used for display presentation (by the psycho and xpyriment backends at least). I don't know exactly what this error means, but the fact that it appears now and not before suggests that it has something to do with updates to the underlying libraries in 3.3.9, and it also suggests that your video card has some issues (in general or with OpenGL specifically).

    As a workaround you can try a different backend. Or you can see if there's something wrong with the video drivers on your system. For example, if you try to run an experiment in a browser, does the browser also complain that WebGL cannot be enabled?

  • Hi Sebastiaan,

    thank you very much for your answer. :)

    I used "legacy" now as backend and the experiment works... not really properly but at least no error message shows up anymore!

    When I run the experiment in a browser, the error: Uncaught ReferenceError: Unknown key 'none' shows up, telling me to see further details in the console, but the console doesn't say anything, so I don't know what the error means....

    I'm sorry if this is a dumb question, I'm a complete newby with OpenSesame :)

    Thank you anyway!

  • Hi @Ari422 ,

    Before you run an experiment in a browser, you should first check whether you're not using any functions that are not supported by OSWeb.

    If you're confident that your experiment uses only supported functionality, but it still crashes with a weird error message, then it's possible that there is a bug in OSWeb. And then you can attach the experiment here so that we can take a look.

  • Hi @sebastiaan,

    thank you very much for your help!

    I checked everything and usually it should work fine, but the online version still crashes with the same error message.

    I tried to attach the file with the experiment, but it says: request failed with status code 413. Maybe the file is too large?

    Thank you! :)

  • Hi @Ari422 ,

    If the file is too large, maybe you can create a smaller and simplified version that shows the same problem? And then post that here?

  • Hi @sebastiaan,

    I attached a miniversion of the experiment. Thank you!

  • Hi @Ari422 ,

    Ah I see! The error message basically says it all: you've listed 'none' as one of the allowed keys in the keyboard_response items, but there's no such key. (On the desktop this doesn't give an error because the desktop runtime simply ignores key names that don't exist.) The solution is to simply remove 'none' from the list of allowed keys.
