Pavlovia sporadically failing to saved data - where can I access logs?

Are you using daisy chaining or displaying the completion code to send the participants back to Prolific?

Running jsPsych experiments from Pavlovia shows how to add daisy chaining.

How to provide return link in jsPsych for participants recruited through prolific?

I have not found any documentation on how to provide a completion return link to Prolific using jsPsych and the Pavlovia plugin. My issue is that I don’t know what does the Pavlovia script do at the end of a jsPsych experiment. Is it okay to redirect inside the on_finish function? ... let pavlovia_finish = { type: "pavlovia", command: "finish" }; timeline.push(pavlovia_finish); jsPsych.init({ timeline: timeline, on_finish: function () { locat…

I just want to make sure that there isnt anything els…

Partial data loss in Pavlovia - empty csv, no log file

Description of the problem: I am running an online study in Prolific (developed the program in PsychoPy 2022.2.4 and adapted to Pavlovia using jsPsych. We are recruiting through Prolific – participants are directed to the experiment link on Pavlovia and at the end of the study they get a completion code on the final page that they enter into Prolific to confirm completion. We are saving the results as CSV files on Pavlovia. We did a pilot of just 6 participants to make sure all was running smo…
