使用 Cloud Firestore 数据库 API 创建云 Firestore 数据库，其中“database_id”为“（默认）”不起作用

Question

I used Google.Apis.Firestore.v1 library to create a cloud firestore for my firebase project as follows, but when running my code I am getting an error related to the database naming I guess, and it has a regular expression format as shown in the error below, and how can I fix this issue?

using Google.Apis.Firestore.v1;

private static FirestoreService _firestoreService;
public static void IntializeFirestoreAdmin() {
   GoogleCredential credential = GoogleCredential.GetApplicationDefault();
   if (CloudManager.Credential.IsCreateScopedRequired)
   {
       credential = CloudManager.Credential.CreateScoped(FirestoreService.Scope.CloudPlatform);
            }
       _firestoreService = new FirestoreService(
        new BaseClientService.Initializer()
        {                 
           HttpClientInitializer = credential,
           ApplicationName = CloudManager.ApplicationName

        });          
            

        }
 public static void AddCloudFirestore() {
       IntializeFirestoreAdmin();
       var mydata = new GoogleFirestoreAdminV1Database {
                LocationId = "nam5",
                Type = "FIRESTORE_NATIVE",
                Name = "projects/" + CloudManager.ProjectId + "/databases/(default)",
                
            };
      _firestoreService.Projects.Databases.Create(mydata, "projects/" + CloudManager.ProjectId).Execute();
}

Error:

If you go through the given method :

FirestoreService().Projects.Databases.Create it has parent as Parameter and databaseId as a Query parameter there is also a try this method section where you can verify your parameters are correct like for example:

using Google.Apis.Firestore.v1;

private static FirestoreService _firestoreService;
public static void IntializeFirestoreAdmin() {
   GoogleCredential credential = GoogleCredential.GetApplicationDefault();
   if (CloudManager.Credential.IsCreateScopedRequired)
   {
       credential = CloudManager.Credential.CreateScoped(FirestoreService.Scope.CloudPlatform);
            }
       _firestoreService = new FirestoreService(
        new BaseClientService.Initializer()
        {                 
           HttpClientInitializer = credential,
           ApplicationName = CloudManager.ApplicationName

        });          
            

        }
 public static void AddCloudFirestore() {
       IntializeFirestoreAdmin();
       var mydata = new GoogleFirestoreAdminV1Database {
                LocationId = "nam5",
                Type = "FIRESTORE_NATIVE",
                Name = "projects/" + CloudManager.ProjectId + "/databases/my-database",
                
            };
      _firestoreService.Projects.Databases.Create(mydata, "projects/" + CloudManager.ProjectId).Execute();
}

Answer 2

var body = new GoogleFirestoreAdminV1Database
{
    Type = "FIRESTORE_NATIVE",
    LocationId = "nam5"
};
string parent = $"projects/{CloudManager.ProjectId}";
var request = _firestoreService.Projects.Databases.Create(body, parent);
request.DatabaseId = "(default)";
var response = request.Execute();

The issue was that I didn't add the databaseId as a query parameter. For more details go to this link https://groups.google.com/g/google-cloud-firestore-discuss/c/EQ-04MnPyLk
