Firebase / Firestore: No document exists but it should

For console output from the firestore call, I am getting No such document!, even though there is a document there (I can see it in the firebase console). Here are some screenshots showing my firestore database:

Here is my code:

    var db = firebase.firestore();

    // Disable deprecated features
    db.settings({
      timestampsInSnapshots: true
    });

    console.log("app.selectedPoolId:", app.selectedPoolId);

    db.collection("pools").doc(app.selectedPoolId).collection("items").doc("items_array").get()
        .then(function(doc) {
            if (doc.exists) {
                ...
            } else {
                // doc.data() will be undefined in this case
                console.log("No such document!");
            }
        })
        .catch(function(error) {
            console.error("Error writing document: ", error);
        });

CONSOLE OUTPUT

app.selectedPoolId: Eamon's pool

This happens when I try to run my hybrid ios/phonegap app from XCode on a device. What am I missing?

UPDATE

I output the doc object's keys and values, just incase anyone notices anything weird.

This code:

for (var prop in doc) {
     console.log("doc key:", prop);
     console.log("doc value:", doc[prop]);
}

Produces this output:

UPDATE

I realized I could get the same document using where on it's collection, but when I try that - it acts as if the function never executes - no error messages, or any other kind of message - it stops after:

console.log("app.selectedPoolId:", app.selectedPoolId);

It outputs the same thing because of the above line, and then stops running without any errors, this is the code I am running to query the collection:

    db.collection("pools").where("name", "==", app.selectedPoolId).get()
        .then(function(querySnapshot) {
            querySnapshot.forEach(function(doc) {
                // doc.data() is never undefined for query doc snapshots
                console.log(doc.id, " => ", doc.data());
            });
        })
        .catch(function(error) {
            console.error("Error writing document: ", error);
        });

Again, no output results form the above code.

Here are the firestore best practices - I looked through them and I think my code complies:

Firestore Best Practices

Solution

  • I am not sure on this but the problem may be that the document name "Eamon's pool" has a space in it and so it not recognizing the whole thing or it is stopping at the first part of the string "Eamon's".

    In the past, when I have used Firestore, the document names I have used contain no spaces and so having space could be the problem.

    Try renaming the document to EamonsPool or a name with no space and try again.
