Upload error (jsPsych experiment) on university JATOS server (v3.5.2)

Our university has a JATOS server (v3.5.2) which we can use to run our experiments, but since a few days I get an error when trying to upload a jsPsych experiment. The error I get is: "You are not allowed to access this page. Please log in" (see attached screen shot), but I'm clearly logged in. I did not have any issues with uploading other jsPsych experiments before (including a pilot version of the experiment I'm currently trying to upload) and on my local JATOS server everything works fine as well. Anything I can do on my end to get rid of the error and upload my experiment?

  • Hi Marita,

    That's odd. The error message is clearly wrong. Just to be sure, can you please try:

    • In your local JATOS, clone the study (on the study bar, go to more -> clone)
    • Export the clone
    • Try to import it on your server.

    The reason I'm suggesting this is that perhaps you have another study with the same UUID (identifier) on the same server but from a different user. Cloning it would give you a new UUID. Let us know if that doesn't work.

  • Another idea: JATOS needs browser cookies to function. Is there a possibility that you deactivated cookies? You can try with another browser to be sure.

  • Hi both,

    Tried both suggestions, but alas.

    Still get the error with a clone version of the experiment. Just to check: wouldn't deleting an experiment from my account also completely delete it from the server hosted by my university? At least, that's what I assumed given the behaviour of my local server. So there shouldn't be any identical UUIDs, correct?

    I also checked whether my cookies were deactivated and tried in a different browser, but still no luck.

    I just tried uploading an example study (the Go/NoGo study), but that also doesn't work, but I have no problems uploading that example study on my local server. I have a feeling it has something to do with the settings on my uni's server end. Any suggestions what the issue might be so I can ask them to fix it? Or is it a known issue with v3.5.2? Perhaps asking them to update to v3.5.5 will solve the issue (my local server runs on v3.5.5)?

    Thanks!

  • Hi Marita,

    That's unfortunate. First to get your questions out of the way:

    Just to check: wouldn't deleting an experiment from my account also completely delete it from the server hosted by my university?

    If 'deleting from my account' means deleting it while you are on your university's JATOS, then yes. But if you just delete your study on your local JATOS then this doesn't automatically delete the study on your university's JATOS.

    So there shouldn't be any identical UUIDs, correct?

    Not sure I understand. A problem with identical UUIDs usually happens if one takes an existing study and just alters it until it is a new study. Problem here is that this study still has the UUID of the old study and importing it to another JATOS where the old study exists, leads to this UUID collision error. The easy solution for this is to clone the study (it gives it a new UUID). I don't I answered your question here - but I leave this here for others that might have this problem :D

    Or is it a known issue with v3.5.2? Perhaps asking them to update to v3.5.5 will solve the issue (my local server runs on v3.5.5)?

    Not that I'm aware of. I just looked again at the commits and couldn't find any changes that would cause such behavior: so I'm pretty confident that your JATOS version is not the cause.

    I just tried uploading an example study (the Go/NoGo study), but that also doesn't work, but I have no problems uploading that example study on my local server. I have a feeling it has something to do with the settings on my uni's server end.

    I have the same feeling. Problem is there can be many causes (and JATOS error message doesn't help here either (sorry for that - I'll try to improve this)).

    • What does the JATOS test page say: my-jatos-url/jatos/test - everything OK?
    • Do you know any other user of your remote JATOS? Do they have the same problem?
    • What is the exact URL you are trying to open in your browser ( I just need the path - domain is not important)?
    • If you click on another non-study page in your remote JATOS: Does it work or do you get the same error?

    Best,

    Kristian

    Hi Kristian,

    Yes, I meant on my university's JATOS (excuse my phrasing). That also kind of answers the UUID question. I've deleted all previous versions of this experiment from my university's JATOS, so there shouldn't be any identical UUID (plus, cloning also didn't help, so I don't think it's an UUID issue).

    I have the same feeling. Problem is there can be many causes (and JATOS error message doesn't help here either (sorry for that - I'll try to improve this)).

    What does the JATOS test page say:  - everything OK?

    Do you know any other user of your remote JATOS? Do they have the same problem?

    What is the exact URL you are trying to open in your browser ( I just need the path - domain is not important)?

    If you click on another non-study page in your remote JATOS: Does it work or do you get the same error?

    Don't know why I didn't think to look there before, but I had a look at the test page as you suggested and it does give me a warning. It says "WARN (wrong protocol)" at "Correct URL host". Plus, I also quickly checked the developers tools and that also gives me an error:

    I've asked a colleague to check whether he has any issues with the server, so we'll see what he says. But looking at these warning/error message, I'm assuming it's on the host server side.

    Forgot to mention this, but the problem actually already start with trying to log in. Sometimes I need to log in 4 or 5 times before I'm even logged in.

    Best, Marita

  • Dear Marita (and others),


    I have the same issue. I'm logged in to the JATOS server at the university of groningen, and after going to 10 or so different pages, I will get similar messages asking to log in, even though on the top right I can clearly see my username being displayed since I am logged in.

    I'm not sure if your comment was also about the RUG servers, I have contacted someone at the Instrumentatiedienst to ask about the error. Hopefully it's just a server-side thing that can be fixed easily.

  • Forgot to mention this, but the problem actually already start with trying to log in. Sometimes I need to log in 4 or 5 times before I'm even logged in.

    Okay, this sounds like there is something wrong with the proxy setting. I'd suggest to tell your IT people to check the proxy's settings. Probably they use Apache or Nginx. The docs have pages for those: http://www.jatos.org/JATOS-with-Nginx.html and http://www.jatos.org/JATOS-with-Apache.html)

    Btw. those 'DevTools failed to load SourceMap ...' you can safely ignore. They don't even originate in JATOS - they come from browser extensions that you are using in your browser. And they only say that some source code couldn't be loaded in the 'pretty' version - but everything is still functional.

    Yep, was talking about the RUG server as well. Great! Could you keep me posted about their responses/fixes?

    @JelleStudentRug If they don't know where to look, we can suggest this?

    Yes, that is a standard error I always get and ignore :) The failed to load error is a bit more problematic though, but hopefully that'll be fixed with the proxy settings. Thanks for your suggestions!

  • They upgraded to v3.5.5 and everything works fine now :) Thanks for your suggestions @elisa / @kri and thanks for checking with RUG IT people @JelleStudentRug!
