We currently enforce a 5 MB limit per individual study run (i.e., per participant), but there is no overall storage limit for a study at this time. This policy may change in the future, although we do not currently have any plans to introduce additi…

Hi, it seems some files needed for WebGazer were not loaded properly. Are they actually in your study assets directory? Does this work on your local JATOS? Best, Kristian
-
Hi, I just released 3.10.5 with the fix to your problem. Best, K.

In the log are some errors, e.g. 2026-06-10 14:50:03,070 [INFO] - gui_access - POST /jatos/import/studyConfirmed (admin) 2026-06-10 14:50:03,187 [INFO] - g.ErrorHandler - JatosGuiException during call POST /jatos/import/studyConfirmed: Couldn't gene…

Trying to download the application-log.gz file also results in a 404 Not Found error. =/ That is strange. Your application.log filename is strange. You are on Windows 11? Can you tell me what files are in your logs folder? It's in the JATOS installa…

Hi Kerwin, is this something new that happened only after you updated JATOS or OpenSesame? Best, Kristian
-
Hi, Can you please post your application.log here? You can send it to me directly. Or you can copy/past here only the part that shows the error/exception. Best, Kristian

Hi Yoran, I can see from your study link, that you are running JATOS locally. That is fine for development, but you'll need an online server to hand our study links to participants. Please have a look at this doc to get more informations: https://ww…
-
Hi Yoran, It's not necessary for each participant to install JATOS on their computer. Can you post/send me the study link? Best, Kristian

Hi Bugay, there isn't a release date yet. Does it work for you to change your filenames to names without spaces? Best, Kristian
-
Hi Büşra, I run your study and it seemed to have worked for me. I run the jzip from Google Drive and the one where you added me as "admin" on Mindprobe. I tried on Cortex and Mindprobe. I couldn't see any problems and in the console were n…
-
Hi Büşra, I wasn't able to download the jzip; it tells me "the file is in the bin". But anyway I might have found the culprit in a similar question. Is it possible you have spaces in the filenames of files you load in your study? The late…
-
Your study uses spaces in the filename `abcde_training_block - NOFEEDBACK.csv` and the latest version of JATOS is stricter with filenames, e.g. doesn't allow spaces in them. I don't use spaces for various reasons in filenames but OSes do allow them,…
-
You can also send it to me personally via this forum. Or my username on Mindprobe is "admin".
-
Can you please send me an example study that doesn't work, either the jzip or make me a member on Mindprobe?
-
Are you using Mindprobe by any chance?
-
Hi Büşra, I tried my studies with OSWeb on Mindprobe on other JATOS installations and they work, as all other studies do too. But we did an update of the JATOS server on the weekend, so I want to make sure that there is nothing that might have cause…

The bug is fixed, a new version 3.10.3 released, and Mindprobe updated. Best, Kristian
-
Hi, the update last night to the latest JATOS introduced two bugs. They are fixed now (version 3.10.3) and Mindprobe is updated. Apologies for any inconveniences. Best, Kristian
-
Hi, it's a little bug that will be fixed later today. Whenever a date is undefined the Date.toISOString throws an error an stops execution. Apologies, for any inconveniences. Best, Kristian
-
Ah, they check for the existence of jatos.js with windows.jatos. I removed the binding to the global window object last released. I never expected such problems. It will return in the next release. It should come out in a couple days. Best, K
-
Hi Kerwin, I'm aware of this problem and the next release of JATOS will have `windows.jatos = jatos;` in jatos.js. This will make it backwards compatible with existing experiments. The release should come out soon, in a couple of days or weeks. Bes…
-
Hi AwaAwa, I had a look at your study. I had to clean up the code a little, somehow you accidentally loaded jatos.js twice. I don't know much about OSWeb but with the help of some AI I think I could pinpoint your problem. In task2.html and task3.htm…
-
Hi, from the JATOS side you seem to do everything correct, but according to the OSWeb docs that you linked, it is ?SONA_ID=%SURVEY_CODE% instead of ?SONA_ID=%SURVEY_ID% . Can this be the issue? If this doesn't solve your problem, I'd recommend aski…
-
Hi AwaAwa, if possible, can you send me all the jzips of your studies that you'd like to combine to one study and the jzip of your combination attempt? I can have a look at it. Best, Kristian
-
If I may continue this thread, it seems that another scenario that leads to this inactivity problem has to do with the fact that in our study, participants sometimes have to wait for one another to finish a previous part. Could it be that waiting ma…
-
Hi Marcel, Your investigation actually helped a lot. I think I know now what is happening. I did some housecleaning of the jatos.js and turned var into const or let where ever possible. jatos.js is pretty old, it was written 10 years ago (and extend…

I also noticed that it can also be a HTTP PUT, not only a POST.

I just tested it with a lab.js study of mine and they send result data to the server. So far, I think the problem is more on the client side's code, your experiment. https://forum.cogsci.nl/uploads/924/WGNIVZ7SY1EG.png
