Question

我正在使用.net core 2+ Web API，试图在Firestore中创建一个集合并向其中添加文档。初始化Cloud Firestore可以正常工作，并且可以通过返回包含初始化项目ID的OK结果来证明。但是，当我要创建一个集合并向其中添加文档时，我开始收到一条错误消息，说我的项目不存在。

为了能够通过我的api与firestore通信，我从NuGet安装了Google的Google.Cloud.Firestore（1.0.0-beta20）。另外，我已经在firebase控制台中设置了new-project（new-project是firebase项目名称）。在我的环境中，还已经为新项目设置了服务密钥-通过向GOOGLE_APPLICATION_CREDENTIALS提供服务密钥路径的路径。最初，我遇到了“名称解析失败”错误，但是在我的环境中设置GRPC_DNS_RESOLVER = native之后，该错误消失了。

这是我与Firestore通信的方式。

var db = FirestoreDb.Create("new-project");

var collectionReference = db.Collection("users");

var docRef1 = collectionReference.Document("alovelace");
var user1 = new Dictionary<string, object>
{
    { "First", "Ada" },
    { "Last", "Lovelace" },
    { "Born", 1815 }
};
await docRef1.SetAsync(user1);

错误消息是

RpcException: Status(StatusCode=NotFound, Detail="The project new-project does not exist or it does not contain an active Cloud Datastore or Cloud Firestore database. Please visit http://console.cloud.google.com to create a project or https://console.cloud.google.com/datastore/setup?project=new-project to add a Cloud Datastore or Cloud Firestore database. Note that Cloud Datastore or Cloud Firestore always have an associated App Engine app and this app must not be disabled.")

我已经关注了文档，并希望在该集合下有一个用户集合和alovelace文档，而不是一个错误。

如何修复RpcException：项目new-project不存在或不包含活动的Cloud Datastore或Cloud Firestore数据库
