Error [Can not GET] when simulating my application with lite-server with typescript

I'm having an error while simulating my application in typescript, the error generated is:

Cannot GET / 

My tsconfig.json file from my application is simple, it only contains the following settings:

{
    "compilerOptions": {
        "target": "es6",
        "outDir": "assets/js",
        "noEmitOnError": true,
        "noImplicitAny": true,
        "removeComments": true,
        "module": "system",
        "strictNullChecks": true
    },
    "include": [
        "assets/ts/**/*"
    ]
}

I'm taking a print from the root of my project if the error is from a repository:

Thank you for your help!
