exception type: KeyError; exception message: u

Hello!

I am a new user to Open Sesame and I find myself trying to program a very basic mouse tracker experiment. I have followed the steps in the Mousetrap response item but when I run it an unexpected error stops the experiment. I will upload the experiment in case anyone knows how to solve this error.

The message on my screen is the following:

Mouse tracker.osexp

Hi,

could you specify which version of OpenSesame you are using? If you are using a version of 3.2.0 or later: have you installed the most recent development version of mousetrap, as described here: https://github.com/PascalKieslich/mousetrap-os#development-version

You can do so via the following command in the debug window:

import pip
pip.main(['install', 'https://github.com/PascalKieslich/mousetrap-os/archive/master.zip'])

Best,

Pascal

Thank you! I updated the latest version and it worked!
