The issue here is that you're returning the array from the callback of the then function, which doesn't do anything. You want to pass the callback into the then function like so:

function doSomething(tasks) {
  let results = tasks.map(task => task.start_date = task.start_date.format("YYYY-MM-DD"));
  return results;
}

function getAllTasks(callBack) {
  models.gantt_tasks.findAll()
  .then(callback)
  .catch(function(e) {
    console.error(e);
    return e;
  });
}

var results = getAllTasks(doSomething);
