Error Message on Pavlovia

URL of experiment:

Description of the problem:
When I uploaded my files from Psychopy and attempted to pilot the study on Pavlovia I keep receiving the following error message:

“-when importing condition: practice_left copy
-extension: practice_left copy currently not supported

The problem is I don’t have a file named practice_left copy in my folder. Please let me know if anyone else has had this problem and how I can get my experiment to run on Pavlovia!

Dear cdo99,

the link your provide points to the login page of GitLab and not your project! So, nobody can access your project. You might want to correct this. Regarding your error message, it tells you that PsychoJS wants to read a file, however, it can’t find it. That’s what you already figured out. Do you have anything named practice_left copy in your experiment? Do I assume correctly that your experiment run locally?

Best wishes Jens

My apologies! I do not have any files named practice_left copy in my experiment so that where my confusion is. My experiment runs smoothly locally on Psychopy and the problem arises when I try to run it on Pavlovia.


you need to provide more information, for instance, by providing access to your project.

Best wishes Jens

Do you have anything called practice_left?

Do you perhaps have a filename with a full stop in the name?

This is the screenshot of the error message that I keep receiving - the problem is I do not have a file named practice_left copy. I do, however have a file named practice_left. I have also attached the csv file for the practice trial here:
practice_left.csv (127.3 KB)

Let me know if there are any other files you may need to help figure this out! Thank you!

I do have a file named practice_left for the practice trial.

Some versions seem to have issues with CSV files. It might be worth trying it as an Excel file.
