Error message when completing experiment #pavlovia

URL of experiment: MentalRotationFinal [PsychoPy]

Description of the problem:


When participants come to the end of the experiment, they receive this error message -

Unfortunately we encountered the following error:

  • TypeError: Cannot read property ‘SERVER’ of undefined

Try to run the experiment again. If the error persists, contact the experiment designer.

Does anyone have any idea how I can solve this?

Thanks! :slight_smile:

When I clicked the link and then aborted I got

  • TypeError: undefined is not an object (evaluating ‘ExperimentHandler.Environment.SERVER’)

Have you made any changes to the experiment settings and direct edits to your JavaScript code?
