When I tried to preview my game, it said this:
Assertion failure: Unable to load project: no JSON model available. Usually this means an error has prevented the browser loading a script. It may be a bug in Construct 2 or a problem in a third party plugin. Check the browser's error console for more information.
Stack trace:

For reference, It was working fine until I added music and the destroy outside layout behaviour.
