Does anyone know what the error "FirebaseError: Unknown field filter op" means?
I working on a Vue project where I store playlists in a Firestore Database, and I want to make CRUD operations.
This error pops up when I try to recieve a single document from the database.
I am not sure where to look for the error.
<template>
<div v-if="playlist">
<h2> {{ playlist.title }} </h2>
</div>
</template>
<script>
import db from '../firebase/config'
export default {
data() {
return {
playlist: null
}
},
created(){
let ref = db.collection('playlists').where('slug', '=', this.$route.params.playlist_slug)
ref.get().then(snapshot => {
snapshot.forEach(doc => {
this.playlist = doc.data()
this.playlist.id = doc.id
})
})
}
}
</script>
<style scoped>
</style>
The operator you use in your query is
=
, which is not a known query operator for Firestore. Firestore uses==
for an equality filter.So:
