Google Firestore DB always returns database not found

I created a Firestore DB in the Google Cloud Console and when trying to do AddAsync for the document I always get database not found.

the code I am using is below. Not sure what I am doing wrong. I followed the

https://docs.cloud.google.com/dotnet/docs/reference/Google.Cloud.Firestore/latest/userguide

I am using .NET client library 4.1.x. I also verified the IAM role and I have datastore.admin and datastore.user for the son any pointers would help.

FirestoreDbBuilder firestoreDbBuilder = new FirestoreDbBuilder { ProjectId = projectId, Credential = tokenCredentialGcp, DatabaseId = "test-details-db" // this is already created in the consolse. }; var db = firestoreDbBuilder.Build(); // FirestoreDb db1 = FirestoreDb.Create(projectId); Console.WriteLine($"FirestoreDb instance built successfully. {db.DatabaseId}"); var collection = db.Collection("testrawdata").Document("testuser"); Console.WriteLine($"Firestore collection reference obtained. {collection.Id}");
