Hi, How do import the properties of the task to JATOS? Do you import a study? If yes, could you please send me the study and I'll have a look what's causing the error. You can send it to lange.kristian@gmail.com. Edit: I mean the .jzip, not the .os…

Hi, my first guess would be a wrong path in your HTML or JavaScript. Glad, you could figure it out. Best, Kristian

You can write to lange.kristian@gmail.com.

Hi! I'm not sure I can be of much help with your problem. Studies can behave differently on a local JATOS than on a remote one (e.g. Mindprobe), just because of normal network behavior, especially if you have large media files. Therefore it's always…

Nice!

Hi, Hm. Difficult to say. Something seem to mess with your study assets folder behind the scenes. The study assets root folder is usually in the JATOS installation folder (name study_assets_root) and then each study has its own study assets folder i…

Hi! What does your browser's console say? Any errors there? Best, Kristian

Hi, I think I've got it working. I didn't actually check if the next OS experiment starts after one finishes (because the experiment was just too long to try to get to the end). But all three work if I start them independently. It was actually not d…

I can give it a try. Can you send me the three OS experiments as three JATOS study zips? Best Kristian
-
I'm pretty sure it's possible to run multiple OSWeb experiments in one JATOS study, each in its own component. Have you tried giving each OSWEB experiment its own subfolder in your study's study assets folder? And in each subfolder you can just copy…

Hi Elise, The behaviour looked exactly the same if I used the "run" button within the JATOS interface (it flashed the end screen then redirected to the JATOS study view immediately), but if I copied a study link and ran it in a new tab, en…

Hi, 'java.lang.OutOfMemoryError' means that your JVM doesn't have enough memory. How much memory does your AWS instance have? It's strange that this happened after you did some housekeeping. Did you maybe reduce the memory while you expanded the dis…
-
Hi! I just tried the endPage.html with my local JATOS but without jsPsych and it worked. So, I'm pretty sure it has something to do with jsPsych messing with jatos.js' endStudy. I assume there is nothing in your endPage.html that closes the tab, e.g…

Hi, After a couple of weeks gone I need to refresh my memory ;) Your participants run your study but sometimes a component is missing result data (as can be seen in JATOS GUI / result page). Now you found the same issue in other studies. We found a …
-
Hi D., I'm sorry to tell you that there is no such recovery of a deleted study possible. Mostly out of data protection / privacy reasons JATOS completely deletes all study data including their results. The only hope you might have is a backup of the…
-
I can see from the error message that you posted, that you have an nginx reverse proxy in front of JATOS and the error message actually originates from there and not from JATOS. I guess something is configured wrong / too strict in nginx. If you goo…
-
Hi, My first guess is that your Nginx is misconfigured, not allowing large uploads. Do you have access to the Nginx config? Can you post it here? Mostly I'm interested in the client_max_body_size. Best, Kristian
-
I see. Basically, I have my study assets outside the jatos directory as a git repository (I wanted to document my work). Good idea. I've seen people doing this. But git usual workflows are not fully compatible with jatos because I can't just clone …
-
JATOS doesn't have a way to ignore certain files in your study assets. But the .git folder is just like any other folder. You can temporarily move it somewhere else and try exporting the study then. Afterwards you move the .git back into your study …
-
Hi, Something seem to go wrong when you export the study. You are right the jzip should be more the 4 byte and the import error in your log just reflects that the zip (the jzip is just a zip archive with a non-standard file suffix) is somehow faulty…
-
If most people on SO agree with the init file ... who am I to disagree :) . And with the 'IF NOT EXISTS' you should be on the save side. Thus, JATOS could access the database as root, provided it is not critical to create a jatosuser like the docume…
-
Hi, I looked again at the study logger source code and found a bug there. This bug seems to have been introduced in version 3.7.2. This bug causes the 'no data' entry in the dataHash field although result data were present. Actually it is a little b…
-
Agreed, 'jatos.submitResultData' only once. Strange. I checked JATOS source code and this should not happen. Maybe jsPsych does something unexpected. Would it be possible to send me your study? Per email (lange.kristian@gmail.com) would be fine. Or …
-
Is it possible that you call the 'jatos.submitResultData' more than once in each component (the second time with empty data)? Can you please post the code here where you use the function?
-
MySQL or H2 - there should be no difference in the 'dataHash'. Strange. Which version of JATOS are you using?
-
Yes, play.http.context in JATOS' production.conf is the way to go here. More info in this page. You can also use the command-line argument -DJATOS_URL_BASE_PATH or the environment variable JATOS_URL_BASE_PATH. Best, Kristian
-
Thank you for posting so others might profit from it. I have a question about the mysql directives in your docker-compose: The command: --init-file /app/data/init.sql is it executed with every docker-compose up? And if yes, wouldn't it try to create…
-
Hi, The 'no data' is written in the Study Log (it's not the application log - the application.log logs admin related stuff while the Study Log logs study run related stuff) when one of the result sending functions is used (e.g. jatos.submitResultDat…
-
Hi, I spend some time with docker-compose but I'm far from being an expert there. I think you don't need to define an extra network - the default network would do just fine. But it also doesn't hurt. But from looking at this doc I think you have to …
