Latest release of the SDK does not work with Google Datastore emulator

Environment details

• OS: MacOS
• .NET version: .Net Core 3.1
• Package name and version: Google.Cloud.Datastore.V1 3.0.0

Steps to reproduce

1. Start the emulator on the command line or via docker eg

 /google-cloud-sdk/platform/cloud-datastore-emulator/cloud_datastore_emulator start --host=0.0.0.0 --port=8081 --store_on_disk=True --consistency=0.9 --allow_remote_shutdown /opt/data

1. Set up the code to connect to the Emulator

_datastoreDb = new DatastoreDbBuilder
            {
                EmulatorDetection = _identityStoreConfiguration.EmulatorDetection
            }.Build();

Fails with:

google-datastore_1  | [datastore] Sep 25, 2020 5:01:14 PM io.gapi.emulators.grpc.GrpcServer$3 operationComplete
google-datastore_1  | [datastore] INFO: Adding handler(s) to newly registered Channel.
google-datastore_1  | [datastore] Sep 25, 2020 5:01:15 PM io.gapi.emulators.netty.HttpVersionRoutingHandler channelRead
google-datastore_1  | [datastore] INFO: Detected non-HTTP/2 connection.
google-datastore_1  | [datastore] Sep 25, 2020 5:01:15 PM io.gapi.emulators.netty.NotFoundHandler handleRequest
google-datastore_1  | [datastore] INFO: Unknown request URI: /bad-request

Now, this is the odd bit. If I downgrade to the older version of the SDK i.e. Google.Cloud.Datastore.V1 2.2.0, it all works fine. I am using the latest GCloud SDK/emulator. Tried with an older version of the SDK, does not work. This is definitely broken in the latest version of the SDK.

Please help.

It should absolutely be using gRPC (and therefore HTTP 2) talking to the emulator. I’m hoping it’ll be easy to sort out on Monday.

This has been released as part of Google.Cloud.Datastore.V1 version 3.1.0 - please let me know if you still have any problems with it.
