How do you restrict the amount of default Javascript autocomplete options?

[kaphula]

I am trying something like this on beforeMount callback:

        monaco.languages.typescript.javascriptDefaults.setCompilerOptions({
            target: monaco.languages.typescript.ScriptTarget.ES5,
            // lib: ["DOM", "ES5", "ScriptHost"] // these are the default libraries for the ES5 target
            lib: ["DOM"], // these are the default libraries for the ES5 target
            noLib: true
        });

But no matter what, I keep getting this exception:
Uncaught (in promise) Error: Could not find source file: 'inmemory://model/1'.
