Make sure non-blocking function can actually complete

I have a SvelteKit API route in this pattern: 
export const GET = async () => {
  const data = await doSomething();

  somethingElse();

  return new Response(data);
};
export const GET = async () => {
  const data = await doSomething();

  somethingElse();

  return new Response(data);
};
How do I make sure that somethingElse (which makes an async HTTP request) actually completes? This pattern works in local dev, but in the runtime it seems to work only intermittently. How can I keep somethingElse non-blocking while still making sure it actually finishes?

You need to use waitUntil I think the code would roughly be something like 
export const GET = async ({context}) => {
  const data = await doSomething();

  context.waitUntil(somethingElse());

  return new Response(data);
};
export const GET = async ({context}) => {
  const data = await doSomething();

  context.waitUntil(somethingElse());

  return new Response(data);
};

solved, I had to use destructured platform and .context.waitUntil
