c# - 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

Question

使用.net core 2+ web api，我试图在firestore中创建一个集合并向其中添加文档。初始化 Cloud Firestore 工作正常，并通过返回包含已初始化项目 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一个文档时，我开始收到一条错误消息，指出我的项目不存在。

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）。我的环境中也已经设置了新项目的服务密钥——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，但在我的环境中设置 GRPC_DNS_RESOLVER=native 后该错误就消失了。

这是我与firestore的沟通方式。

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);

错误信息是

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.")

堆栈跟踪是

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。
