MongoDb in Unity WebGL
Hello people.
I'm trying to access a Mongodb in a WebGL project.
Here is an excerpt from my DbConnector:
using System;
using MongoDB.Driver;
using UnityEngine;
public class DbConnector : MonoBehaviour
{
private static MongoClientSettings _settings = new MongoClientSettings
{
Server = new MongoServerAddress("localhost", 27017),
};
private static MongoClient _client = new MongoClient(_settings);
private static IMongoDatabase _userDatabase;
public static IMongoDatabase GetDatabase(string dbName)
{
switch (dbName)
{
case "user":
if (_userDatabase != null)
return _userDatabase;
break;
}
return null;
}
private void Start()
{
try
{
_userDatabase = _client.GetDatabase("user");
Debug.Log("Loading userdb complete!");
}
catch (Exception e)
{
Debug.Log("can't load user db from server: " + e);
}
}
}
In the editor this works fine, even if the Mongodb is on a server and has authentication.
As soon as I upload it, however, I get this error:
MethodAccessException: Attempt to access method 'MongoDB.Driver.IMongoDatabase.GetCollection' on type '' failed.
The script 'DbConnector' could not be instantiated!

The app itself goes. Only not the connection to the Mongodb.
The dlls I have among other things from: https://github.com/mongodb/mongo-csharp-driver
or from: https://github.com/mongodb/mongo
or here: https://github.com/Julian23517/Unity-mongo-csharp-driver-dlls
The latter from the post (at the bottom) by: https://answers.unity.com/questions/618708/unity-and-mongodb-saas.html
Nothing has come up with a solution yet.
Here are my ProjectSettings:
