URL of experiment: Description of the problem: Hello everyone, I have seen this topic before, but unfortunately, I did not find a straightforward solution. I am currently running an online experiment. According to the subscription system and the session counter in Pavlovia, I should have 27 sess…

Hey Mila, Pavlovia is quite careful at checking whether all the data from an experiment is received and saved. If all of this goes well, your participants get to see a green dialogue box saying “Thank you for your patience”. Before that, it could be that not all data is saved. Could it be that part…

Dear Thomas, Thank you for the response! I am not sure this is the case, because even incomplete data with just 5-4 trials and forced ending of the experiment is saved. What happens might be much simpler - people just click on the link and don`t complete the experiment. So the sessions count goes u…

Hi @thomas_pronk , I had the same situation as @mila.marinova for my very first two pilot participants. Since I talked to my participants, I was pretty sure that they did everything right during the task; no early ending. However, for one task, I can see that the latest data save was within a day o…

That’s strange! If participants arrived at the green dialog box that says “thank you for your patience”, then Pavlovia confirmed to PsychoJS that all the data has been received succesfully. Two questions: Did the task have active status? (if it’s piloting mode, then the data isn’t stored on Pavlov…

Hello Thomas, I also continue to experience data loss (around 30%). My participants also confirmed that they completed the full experiment and there were no warning/error messages. Indeed this whole situation is a bit strange, so I will be very thankful if you can have a look also at my project ( ht…

@milana.marinova, I can’t see your experiment yet. Could you make me a member of your repo? Searching for experiments on Pavlovia — PsychoPy v2021.1 I would like to mention that participants can be a bit naughty, saying that they did complete it while they actually just aborted the experiment. Havi…

Hi @thomas_pronk , I was trying to add you to my project but looks like there are two Thomas Pronk (please see attached). Here’s my gitlab page: Sign in · GitLab . Just to clarify, I used jsPsych, not Psychopy, so my participants won’t be seeing the green dialogue box. But it looks like the problem i…

I’m @tpronk. I’m a bit less proficient with jsPsych, but the same principle applies as far as I know: Pavlovia sends a reception confirmation and if that’s in, you can be quite sure it’s stored in the DB. I’ve had a couple of other jsPsych requests, so I’m bundling them up to tackle at once; could t…

@Lillian_XU , I just encountered another user that reported an issue with saving, but also found out what the problem is. Perhaps the problem is similar to yours? jsPsych experiment, token randomly consumed, no data stored - #3 by DonShirley

@Lillian I can’t get into your gitlab project. Meanwhile I’ll dive into solving the other jsPsych issues, which might also solve yours: JsPsych Saving Options on Pavlovia - #18 by F_Elisabeth jsPsych experiment, token randomly consumed, no data stored - #5 by Lillian_XU
