I'm trying to read data from my Firestore database in my cloud functions.
My Database:
cases -> 1 -> (number) min: 1
My code in my function https.onCall( async (data, context):
if(!data.caseslot) {
console.log("no caseslot");
//throw exception
}
else{
console.log(data.caseslot); //this logs me 1
var db = admin.firestore();
db.collection('cases').doc('${data.caseslot}').get().then(snapshot => {
console.log(snapshot.data().min); //"TypeError: Cannot read properties of undefined (reading 'min')"
}).catch(reason => {
console.log(reason);
});
}
At this point, I don't know what I'm doing wrong. I double checked my database...
You have enclosed ${data.caseslot} in single quotes, you have to enclose that in back ticks
if (!data.caseslot) {
console.log("no caseslot");
//throw exception
} else {
console.log(data.caseslot);
var db = admin.firestore();
db.collection("cases")
.doc(`${data.caseslot}`) //enclose in back ticks (``)
.get()
.then((snapshot) => {
console.log(snapshot.data().min);
})
.catch((reason) => {
console.log(reason);
});
}
