I am running into an issue at the end of experiments built with
lab.js – Pavlovia’s integration appears to be failing, and loses all experimental data. This is observable with arbitrary experiments, that run fine on other platforms. Here’s the error message:
[labjs-pavlovia plugin 3.2.5] Error
- when uploading participant’ results for experiment: felixhenninger/stroop-demo
- when saving data from a previously opened session on the server
- unable to JSON decode the value: Expecting value: line 1 column 1 (char 0)
It looks like the server infrastructure is expecting a different data format from the one that the Pavlovia JS plugin is sending?
Any hints would be much appreciated. Many thanks,
