I'm encountering this error when trying to launch a course I uploaded (from course_package) in the AU > Launch

Steps to reproduce:

1. Launch the CTS client http://127.0.0.1:3399/client/#/ and login
2. Click New Course and upload a course from the course_package directory
3. Test the uploaded course, create an Actor
4. In the Assignable Units Pane, click Launch

This is my cts/.env configuration

I've read in the other issues that it may need to install an actual LRS, is this also the case here?
