followUser: [
_id:String
]

I'd like to replace it

followUser: [
_id:String;
username:String;
profileImage:String;

This method of getting the follower object in the user database is not correct, and you have to make complex queries to discuss updates and make queries. It would be better to have a separate follow database. To solve your problem, the best way to write a script is to find all the users and create a separate function that will create the array you want and save it in that user. You can use Promis.all() for this. for example:

        User.find({}) 
             .then((users)=> {  
                 Promise.all(users.map(user => {
                 
                  return updateFollowerArray(user)
                })) })
