Is this your development or a deployed production environment?
How are you running your project?
Are you getting 404 errors on that file? If so, please show the server log with the failing request.
Side Note: When posting code here, enclose the code between lines of three backtick - ` characters. This means you’ll have a line of ```, then your code, then another line of ```. This forces the forum software to keep your code properly formatted. (I’ve taken the liberty of fixing your original post. Please remember to do this in the future.)

That may well be true in this case, but might be something you don’t want to do.
In general, if you have “site-wide” static resources, they’re generally better located at the project level and not within an app. The app’s static directory should be reserved for resources used by that app.
