URL of experiment: Andrew Vu / N-back task with visual stimuli · GitLab
Description of the problem:
After trying to pilot the n-back experiment on pavlovia.org, these errors come up as I enter the 1st trial loop, which then creates a 404 error immediately aborting the experiment.
This is the “TypeError: Cannot read property ‘0’ of undefined” that occurs on Chrome.
This is the “TypeError: pos is undefined” that occurs on Firefox.
I am unable to upload another image to show the experiment flow, but the error probably occurs around the ‘// Initialize components for Routine “N_back_1_Trial”’ portion of the “n-back.js”.
The software platform is PsychoJs, the platform version is 2020.1. My partners have suspicions that the errors are because of the “.xlsx” files used as the experiment conditions.
Any help is appreciated.
