Edit: I had forgotten to include completedCallback as an argument to the definition of my pavlovia finish trial, which is what was causing an error. The argument seems mandatory, although not sure if it should be.
Thanks for your work on this @thomas_pronk ! Another interesting pondering I have is why only the main data object from jsPsych is saved. For instance, I would like to save the interaction data but I am struggling to get it to work properly. My central attempt consists of adding a _save() call within the plugin trial method (in the case: ‘finish’ block, before await _finish) and data do get end up saved but I am getting an error on the screen to the participant.
I am attaching the file I am using (this is essentially a modified version of your script). Any help would be greatly appreciated! NB: The file is saved as .py but is actually a .js file – the forum does not let me upload .js files.
