I keep receiving a ‘Psychopy 3 error’ message when trying to open a .cvs file. I rather new to the software so I’m not sure if I’m doing something. The error message reads the following:

Traceback (most recent call last):
File “/Applications/PsychoPy.app/Contents/Resources/lib/python3.6/psychopy/app/runner/runner.py”, line 255, in loadTaskList
File “json/init.pyc”, line 299, in load
File “json/init.pyc”, line 344, in loads
json.decoder.JSONDecodeError: Unexpected UTF-8 BOM (decode using utf-8-sig): line 1 column 1 (char 0)

The error is related to a .json rather than .csv file. Could you please show us exactly what code you are using?

However it seems that this error might not be related to your code per se. What happens if you push the “Run experiment” button rather than “Send experiment to Runner”?
