I am on Node 8 with Sequelize.js

Gtting the following error when trying to use await.

SyntaxError: await is only valid in async function

Code:

async function addEvent(req, callback) {

    var db = req.app.get('db');

    var event = req.body.event



    db.App.findOne({

        where: {

            owner_id: req.user_id,

        }

    }).then((app) => {



                let promise = new Promise((resolve, reject) => {

                    setTimeout(() => resolve(done!), 6000)



                })



               // I get an error at this point 

               let result = await promise;



               // let result = await promise;

               //              ^^^^^

               // SyntaxError: await is only valid in async function

            }

    })

}

Getting the following error:

               let result = await promise;

                            ^^^^^

               SyntaxError: await is only valid in async function

What am I doing wrong?
