How to add Firestore emulator support? about firebase-unity-sdk

A quick Google search brought me to this post: https://stackoverflow.com/a/62171642/12975006

Could you ensure that your security rules in the emulator are sufficiently permissive to allow the writes?

I've logged b/202835732 (for Googlers) to see what we can do to improve the error message produced when a Firestore operation is rejected by security rules.

Hi @dex3r. The Firestore emulator is working fine for me. I'm going to need some more information to help out.

1. Can you enable debug logging in Firestore? To do this, call FirebaseFirestore.LogLevel = LogLevel.Debug; before doing anything else.
2. What version of the Unity SDK are you using (please use the latest, 8.3.0)?
3. What OS are you running the Unity Editor on (e.g. Mac, Linux, Windows)?
4. What OS are you running the code on? (e.g. Android, iOS, via play button in Unity Editor)?
5. What command line did you run to start the Firestore emulator?
6. Do you have the latest version of the Firestore emulator?
7. Can you attach the full log output (e.g. Unity Editor log, Android logcat)?
8. Can you show a larger code snippet of your code?

After answering these questions, could you create a minimal app that you use to reproduce the issue? Then I could clone it and try it out for myself to see if I can reproduce what you're seeing.

Test code (empty scene with only this object):

using System.Collections.Generic;
using System.Threading.Tasks;
using Firebase;
using Firebase.Firestore;
using UnityEngine;

public class FirestoreEmulatorTest : MonoBehaviour
{
    async void Start()
    {
        Debug.Log("TEST START");
        
        FirebaseFirestore.DefaultInstance.Settings.Host = "localhost:8080";
        FirebaseFirestore.DefaultInstance.Settings.SslEnabled = false;
        FirebaseFirestore.DefaultInstance.Settings.PersistenceEnabled = false;

        FirebaseFirestore.LogLevel = LogLevel.Debug;
        
        await WriteToEmulator();
    }
    
    async Task WriteToEmulator()
    {
        var docRef = FirebaseFirestore.DefaultInstance.Document("testL/test");
        var documentData = new Dictionary<string, object>();

        await docRef.SetAsync(documentData);
        Debug.Log("Write done");
    }
}

2. 8.3.0
3. Windows 10
4. Editor
5. firebase emulators:start
   
6. Yes

8. See above

Hmm everything looks good. I have no idea what that error means. Since "permission denied" is in the message, is there a chance that your firewall (e.g. Windows Defender) is blocking the connection?

Also, could you try exiting the Unity Editor and deleting the local cache by running

rd /s /q %USERPROFILE%\AppData\Local\firestore

[dex3r]

I've turned off the windows firewall but the problem persists. Removing the cache also did not help.

@dconeybe thank you, that was it. I would have never guessed it was this simple since the error message was non-existing on google :)
