Nodejs Firestore: Returning nothing

I am using firebase to check a users punishment history, and when I call it: I want it to return the array of embeds to post rather than just that. I am awaiting the function so I'm kind of confused why this is happening

This is what happens in the console.log:
```
[AsyncFunction: CheckHistory]
```

CALL

let hist = await CheckHistory(id);
console.log(CheckHistory);

FUNCTION

    async function CheckHistory(user){
      CheckBan(user);
      let historyArray = [];

      const colRef = db.collection('punishments')
      colRef.where('user', '==', user).get().then(async querySnapshot => {
        length = querySnapshot.size;
        if (querySnapshot.empty){
          console.log(querySnapshot.size)
          return 0;
        } else {
          let docs = querySnapshot.docs;
          for (let documentSnapshot of docs) {
            const revoke = documentSnapshot.get('revoke')

            let active = documentSnapshot.get('active')
            if (active = true){
              active = "Active"
            } else {
              active = `Revoked for ${revoke}`
            }
            const mod = documentSnapshot.get('mod')
            const reason = documentSnapshot.get('reason');
            const time = documentSnapshot.get('time');

            let type = documentSnapshot.get('type');
            if (type == 1){
              type = "Blacklist";
            } else if (type == 2){
              type = "Dayban";
            } else if (type == 3){
              type = "Warning";
            }

            const username = await API.getUsernameFromId(user);
            const modname = await API.getUsernameFromId(mod);

            const historyEmbed = new MessageEmbed()
              .setColor('#0099ff')
              .setTitle(`'Punishment of ${username}:${user}`)
              .setDescription(`This is a punishment log.`)
              .addFields(
                { name: 'Status', value: `${active}`},
                { name: 'Moderator', value: `${modname}:${mod}` },
                { name: 'Reason', value: `${reason}` },
                { name: 'Type', value: `${type}` },
                { name: 'Time', value: `<t:${time}>`}
              )

            historyArray.push(historyEmbed);

            if (historyArray.length >= length) {
              return historyArray;
            }
          }
        }
      });
    }

As stated by @Sergey Sosunov:

You forgot to actually return anything from your method, you should
return colRef.where('user', '==', user).get().then....
Or to change .then() callback approach to actually await one. Like:
const querySnapshot = await colRef.where('user', '==', user).get(); 
and so on.

Also, the way you call the function only returns function definition; you should pass with parameters or print the variable value equal to your function. For example:

//Sample function
function test(id) { return id; }

//Returns function definition
console.log(test) 

//Returns function value
console.log(test(1))

//Print variable value
let x = test(1)
console.log(x)
