Hi,
This error can happen when the JATOS server side closes the batch session expectantly. This is definitely not a normal thing to happen. Maybe your server runs unstable? Can you monitor the server? Did it crash at one point? How is CPU, memory and disk doing at the server?

When this happens on a participant's page, the experiment administrator interface appears to be all right, and the pages of other participants who are conducting the experiment at the same time also appear to be all right. Therefore, I think this problem may only occur in the page transmission of a single participant.
Thank you for your reply. This server is not owned by me personally, but I will try to inquire about the server's operational status later. By the way, it is indeed a very lightweight server, possibly with only 2 cores and 2G of memory.

2GB should be okay for a small JATOS instance with not too many users and participants. Do you have access to JATOS administration page, /jatos/admin? If yes, then check the logs: click Logs and then "application.log". Search for any exceptions and errors.

I don't know what happen. There seems to be a lot of warnings. But the time stamp seems to be inconsistent with the time in my area. It is difficult to see which warning is related to the failed participant.

After time conversion, I found that the last error should have occurred around 3.20 8:00 on the JATOS server time.

There is a lot going on in your log. Can you please copy-paste it here as text (instead of a screenshot). I can comment easier on text.

I cannot find anything in the log that explains the error “This study run is invalid”.
There are no hints for a lack of memory or disk space (CPU is usually not a problem with JATOS). But this doesn't mean that memory or disk is not a problem.
But there are a couple of strange log messages:

Your study run cannot access an image with the path Study2-empathy/H.png. Maybe the path is wrong? Check the component with the UUID 719651a6-5300-47c1-8b83-dfdae2c1933d.

The batch channel for one study run got opened 10 times in short succession. Usually only once. Strange! Maybe reloads?
2023-03-20 08:00:08,980 [INFO] - g.ErrorHandler - not found: Requested page /jatos/import/studyConfirmed couldn't be found.
That is a strange error. The endpoint exists for a HTTP POST. Do you call this endpoint somehow manually with a different HTTP method? Why? Better use the JATOS API.
That's all I can say about the log. Have you got any monitoring of your server? And which version of JATOS do you run?

I just ran a complete study during this time and some of the problems disappeared and some remained. The problem of opening the batch channel multiple times in a short period of time should always be present. It is not clear what is causing these problems. However, there is nothing unusual about the experimental run page or the administrator interface, except for two extra data records (albeit records without data files).
I built this JATOS server four months ago following a tutorial I found on the web, and have not opened the server backend since then. Everything is done on the web page. I don't know if these problems stem from the server side build process. Maybe I should take the time to rebuild the server? I don't know much about this aspect of server building.
Thanks for going out of your way to answer this. The exceptions are indeed not related to the "invalid" exception. My JATOS version is 3.7.4. system information is attached below.
This is probably a very tricky problem. If you find any solution to this problem, thank you for suggesting it. I will check the log file in time the next time the "invalid" is displayed.

Good to know, your server did not crash recently (Uptime: 2570h 49m 24.53s) :)
Max memory: 1.0 GB - 1 GB just for JATOS should be enough for running just one experiment
You could consider updating your JATOS to 3.8.1. I don't think this will fix your issue but there are some performance improvements in the recent releases that might help especially since you have only 1GB memory on your server.
And what's about those file access issues? Did you check the paths in your study? E.g.
2023-03-20 07:57:30,280 [INFO] - c.p.StudyAssets - .viaAssetsPath: You tried to access the file Study2-empathy/H.png but it seems you have no access rights.
But my main concern are these multiple c.p.GeneralMultipleBatchChannel - .open. There should only be one. And I do not really have an idea what's going on here.

Just now this issue happened again——a participant's screen displayed "invalid". I checked the logs during this period and didn't see any strange exceptions. I have already checked the path issue, it doesn't occur in my local running, but it happens after importing the experimental file to the server. Tonight I will try to update the JATOS server to the latest version. Ideally, it would be best to rebuild the server directly.

My god! When I updated to the latest version, the structure of the data I collected changed dramatically, which meant that I had to refactor my data analysis code. Is this a normal change after the update? Or did I make a mistake somewhere.

Sorry for the late reply. Can you please elaborate on how the structure of your data changed? What was it before and how does it look now. You say the line breaks disappeared?

St-ZFeng
commented on June 11, 2024
Never mind, I have already solved this problem.
Yes, the line breaks did disappear. I wrote a program using JSPsych, and after updating JATOS to the latest version, the line breaks in the data were removed, resulting in all the CSV data being in a single row (there should have been multiple rows, with one row of data for each component). The same thing did not happen in version 3.7.4, so I have now reverted back to that version.
I wrote a Python program to deal with the line break issue, but the process was a bit convoluted, especially since my HTML page contained a lot of nested quotes.
I didn't do any further testing, so I don't know if this problem is caused by issues with the latest version or compatibility issues between two versions. Perhaps it only occurs in my study.

I see. I just tried and can confirm. This should not happen. Result data should be allowed to have line-breaks. I created a new bug issue (#285) for this.

I was sick the other day, so a lot of work has been put on hold, and I apologize for not responding to your message until now.
If there were no nested quotes in the html, then this problem would be easily solved by simply inserting line breaks after a specific number of quotes (usually two times the maximum number of columns). However, in Jspsych's data the entire content of the html is usually recorded, for example <p style="....."> this type of tag information, which creates nested quotes.
The pairing status of each quotation mark is first checked one by one. If a character is a paired quotation mark and its next character is not a comma but an unpaired quotation mark, a line-break is inserted between the two. This usually results in broken data. Thanks to Jspsych's data format, which starts with multiple consecutive nulls from the third line, the second step is to merge all lines that do not start with consecutive nulls with the previous line. But I'm not sure that this method works in all cases. Please be sure to perform a data backup before this operation.

Hi Kristian,
thank you so much for sharing JATOS with us. We are having a similar problem. Our institute's server was updated about six weeks ago, and since then about 25 % of our participants have been receiving the message "The experiment failed to load." at a seemingly random moment during the experiment. Curisously, we have been collecting data for this experiment since January (about 65-70 datasets collected) and have not changed anything about this experiment since then. So far, we have never had this problem.
Unfortunately, I can't reproduce the problem myself, but a student sent me a screenshot their console output. Unfortunately I can't make sense of it and don't really know where in my could I should try to fix it. All images are available and are loaded properly for other participants. The problem occurred on different OS and in different browsers (including Chrome and Firefox).
Regarding the issue "Internal JATOS error during /publix/[jatos study code]. Check logs to get more information." others have reported in the cogsci forum: We had a similar problem about two weeks ago (a month after the update), when we out of a sudden got the same error message every time any Jatos link was opened in a browser where a Jatos link had been opened at some point before. This problem can be fixed by clearing the browser cache (even though this means all participants need to be instructed to empty their browser cache first).

Hi!
It would have been better to post this kind of question in the CogSci forum since it's more a support kind of question. And secondly it would have been better to post the question in a new thread or issue; just to keep things separated and clean. Sorry for nagging so much ;). But, now, since we are already here ... you have two issues as far as I can see: 1) the connection problems, and 2) the Internal JATOS error due malformed cookies.
About 1) The two screenshots show that your participant was not able to reach the JATOS server (lots of connection timeouts, batch channel heartbeat fail, websocket connection fail). So something was broken, either the JATOS server or something between the server and your participant (router, network etc.). Here I can't help much since I do not operate this particular JATOS server nor the other parts of this infrastructure. I'd recommend to contact your admin.
About 2) JATOS has a problem dealing with old cookies from older JATOS versions after an update with certain browsers. This is a one-time thing and after one deletes those cookies JATOS works normally. But it is a bug and the next version (v3.8.2) will have a fix for it.
Best,
Kristian

It doesn't seem to be possible to update directly in the existing server yet, do I need to reinstall the server or will this feature take a few days to implement? My current version is 3.7.6.

Oh, no more questions. Probably an internet connection issue, even the 3.8.1 update doesn't work. I will take some time to rebuild the server. After all, this is the only viable way to get the newest version for me.
Thank you again.

commented on June 11, 2024
Yes, looks like some connection issue.
And a hint: you can force an update to a certain version by using the 'version' query parameter. Sometimes JATOS doesn't acknowledge the newest version. E.g. for cortex.jatos.org it would be:
https://cortex.jatos.org/jatos/admin?version=v3.8.2
