That is one solution :) My guess on why it did not work with a simple 'jatos.onLoad' is that the execution of your JavaScript never reached that point in your code. But to confirm I'd have to see your code. Anyway, with using a button you circumvent…

Hi Cristina, The code you posted looks fine. Do you get any error message in your browser's Developer Tools? And if you don't want to submit any result data you can just use jatos.startNextComponent directly without calling jatos.submitResultData fi…
-
Version 3.5.6 is fine. It sends the result data in the background and waits until they are all transferred before it finishes the study (so the 20s pause in the end of your experiment shouldn't be necessary). What confuses me is that your study runs…
-
If you are using JATOS you can use the 'End Redirect URL' field in your study's properties to direct participants to a survey link at the end of the experiment: http://www.jatos.org/End-page-after-your-study-finished.html#3-study-properties-end-redi…

May I ask which JATOS version you are using? In older versions of JATOS + OSWeb the behavior you described was possible but this was fixed a couple versions ago.

Hi Romàn, Do you mean with 'deleted participants' that you deleted the study results (by pressing the red button in the study result page and confirmed the dialog)? Then there is no solution to get back those data - unless you have a backup of your …

Hi Laura, Can you tell us a bit more about the failing data transfer? Do you get any error message in the developer tools of Safari? Does it fail always at the same point in the experiment? Does it happen with all participants using Safari or can so…

I admit the error message is confusing here. I will change it to something more meaningful that mentions that cookies should be allowed. But the reason that the error msg mentions something specific as the result ID is okay. The JATOS internal flow …

Hi! JATOS needs cookies to work (first party cookies only). JATOS uses cookies to pass on information about the study run (e.g. study result ID, batch ID) from the JATOS server to the participant's browser where it is picked up by jatos.js. JATOS do…

Hi Roger, About you first question, customization of the max batch workers reached message: unfortunately not, there is no easy way to customize this. It's hard-coded into JATOS without the possibility to configure it. And about the second question…
-
Hi Mireia, It's difficult to say something about your problem when there is no way to reproduce the problem. And I'm reluctant to try the provided link to your study, that takes 25-30 min, if there is a high chance that the problem will not turn up.…
-
Hm. I'm not sure if this is a problem of your experiment, OSWeb, JATOS or a network problem. But maybe with some questions we get somewhere: Is there a way to reproduce the problem so we can have a look at it? Can you give us a JATOS study link or a…
-
This reminds me of another recent question here: https://forum.cogsci.nl/discussion/6503/export-trial-by-trial-data-from-an-online-osweb-exp-running-in-jatos How do you do your experiments? With OSWeb this might be difficult but if you program it yo…

Hi Dror! You can sent the result data of your experiment to any server you wish, not only JATOS. Your R server just need to have an HTTP interface that allows this. And there my knowledge of R ends: I don't know if R can be set up as a server this w…
-
@ed1334 I guess 'pick up error messages' means in the browser occurring errors are being sent back to JATOS and saved in JATOS' log. Automatically JATOS or jatos.js doesn't pick up any error messages that happen in the browser. But one can do this t…
-
Nice to hear it works now. I intend to update experiments.jatos.org soon, just waiting for some quiet time when nobody's using the server, probably this weekend is a good point. Best, Kristian
-
JATOS doesn't care of the type of data you put in the results or the uploaded files. It can be text, images or in your case video. So yes. But the other question is whether OSWeb supports this and there hopefully others can help @Daniel, @sebastiaan…

I'm not an expert in Traefik, just using it every now and then. But from there documentation (https://doc.traefik.io/traefik/middlewares/buffering/) I'd say it's enough to set maxRequestBodyBytes.
-
Hi Deiniol, I uploaded your combined study to your OneDrive: the file posLeft.jzip. Please check that everything is correct, e.g. I think I missed to copy your study's comments. Apart from that, I think, it works. The trick was to use the path with …

Hi Felix! I fixed the issue. More about the reason you can find in the Github issue: https://github.com/JATOS/JATOS/issues/208. The new version (v3.5.8) is still in pre-release but I installed it already on cortex.jatos.org for you to try out. I tri…

Hi Yvonne, Sorry for taking so long to answer. Apart from the 'bad request' error you also have an 'EntityStreamException' which can or can not have something to do with the first error. This 'EntityStreamException' just states that the request wasn…
-
You would have to specify this in the instructions, there is no way to configure this in JATOS. And it's better to put this in the early instructions in MTurk that appear before the worker accepts the HIT.
-
Hi Felix, I checked with Safari and had the same error as you: JATOS isn't allowed to run a study with the study result ID ****. Then I tested it on Chrome and Firefox and it worked. Then I tested with different worker types, Personal Multiple and G…
-
Interesting. It would be strange that Safari somehow alters the URL query parameters. But I'll test it: I do not have a Safari browser at hand right now but I'll test it this evening on another laptop at home and come back to you. Kristian
-
Hi Yvonne, Someone asked a similar question on Github (https://github.com/JATOS/JATOS/issues/204). I think there we couldn't find the reason for the error due to time constrains. But one possible cause was that somehow the 'srid' parameter in the U…
-
I'm a bit hesitant to give an definite answer. This question is in the OSWeb forum and I don't know much about OpenSesame/OSWeb. But I know about JATOS and from JATOS point of view it is no problem to deliver arbitrary files and in this JATOS is not…

Hi Felix, That is strange indeed. I just tried too, like you said, same email for Worker Sandbox and Requester Sandbox, and it worked fine like before. You can try it too: https://workersandbox.mturk.com/requesters/A3ER60IEU77H9M/projects?ref=w_pl_p…

Hi Felix, I just tried it out with MTurk Sandbox and it worked. Try it yourself: https://workersandbox.mturk.com/?filters%5Bsearch_term%5D=kristian&page_size=20&page_number=1&sort=num_hits_desc&filters%5Bmin_reward%5D=0 I did nothing…
