(Node J.S.) SyntaxError: Unexpected token function on an async function

So I'm trying to use async/await but i get this error:

async function something(options) {
  ^^^^^^^^
SyntaxError: Unexpected token function

Here's the code:

var request = require('superagent');

async function something(options) {
    let response = await request.get("apiurlblabla");
    if(response) {
      .query(({'queryqeureur}))
      .query(({'uqeryqery'}))
      var jsonString = JSON.parse(res.text)
      console.log(jsonString.propertyblabla);
      console.log(jsonString.propertyblabla)
    }
}
