jsPsych experiment, token randomly consumed, no data stored

Hi @thomas_pronk , thank you very much for sending me to this post! I took a look at my three tasks and found that the one with data loss is the one that generates the largest data file (around 110 KB, still small compared to other’s data in MB). I did save the data successfully once when I did it without any redirecting afterward. Don’t know if redirecting plus large data size is the cause?

After reading all these posts, here’s my action plan:

  1. Try to get Pavlovia’s receipt confirmation before or during redirecting.
  2. Try to insert a delay before redirecting (if the first method does not work).

One question: is there any information on how we can get Pavlovia receipt confirmation? Thank you!

Best,
Lillian
