The last component of the study sometimes does not want to finish and save the data

[mmalikovic]

What would you like or expect to see?

I expect the results of the experiment created in lab.js to be saved in the JATOS platform

What is currently happening?

I made an experiment in lab.js. Sometimes the results are neatly saved on JATOS, and sometimes the last component remained "forever" on the screen and the page with "This study is finished. Thank you for your participation" does not want to load. I don't see any logic or regularity in that and I don't see what have caused this behavior. The experiment is complex and consists of over 20 components (several questionnaires, several tests programmed in JavaScript, etc.) and it also collect data about mouse movements in "event stream" form. So the final txt file with the results of one participant has about 4 MB (in case it succeeds in closing).

Please describe the steps needed to reproduce this phenomenon

I am attaching the whole experiment ->
agresivnost-1-anksioznost-1-2024-05-03--10_58.study.json
If you go through it all when it is on the JATOS platform (it takes approx. 20 minutes) then at the end sometimes the data is written and sometimes not (and I don't know what it depends on)

Finally, please tell us which browser you're using (and the version thereof)

The experiment is opened in various browsers because the subjects have to open it themselves
