Firebase firestore - Data must be an object, but it was: a custom Object object

I'm using Firestore in conjunction with realtime database in order to provide a user presence system for my application.

Update: article I followed

https://blog.campvanilla.com/firebase-firestore-guide-how-to-user-presence-online-offline-basics-66dc27f67802

In one of the methods I use this code here:

const usersRef = this.$fireStore.collection('users').doc(uid)
const whoIsOnlineRef = this.$fireDb.ref('.info/connected')

whoIsOnlineRef.on('value', (snapshot) => {
    this.$fireDb.ref(`/status/${uid}`)
        .onDisconnect()
        .set('offline')
        .then(() => {
          usersRef.set({ online: true }, { merge: true })

          this.$fireDb.ref(`/status/${uid}`).set('online')
        })
})

The .set method, however, is giving me the error mentioned in the title and I can't quite understand why. I'm simply passing a javascript object to .set method and this should technically work.

Can you spot what is wrong with the code?

Looks like the reason why this wasn't working is that the code was running on the server in an SSR application.

I moved that very same logic to the browser and it started working nicely. I still don't see why this wouldn't work in the server as, at the end of the day I was still passing a simple js object to the .set() method.

Either way, there you have it
