Trying to get inferred type of an identifier with @typescript/vfs

index.ts

import {
  createDefaultMapFromNodeModules,
  createSystem,
  createVirtualTypeScriptEnvironment,
} from "@typescript/vfs";
import * as ts from "typescript";

const fsMap = createDefaultMapFromNodeModules({
  target: ts.ScriptTarget.ES2015,
});
fsMap.set("index.ts", `const hello = 'hi';`);

const system = createSystem(fsMap);
const env = createVirtualTypeScriptEnvironment(system, ["index.ts"], ts, {});

const result = env.languageService.getTypeDefinitionAtPosition("index.ts", 6);

console.log(result); 
// => [] 
// 🤔 It's not undefined, but there's no type here…
