google-cloud-dotnet: "Transport Closed" and "GOAWAY received" error on StreamAsync

For some days using firestore. Sometimes I got this error on using this library on aws dotnet lambda with this code

<PackageReference Include="Google.Cloud.Firestore" Version="1.0.0-beta02" />

////

var docID = await firestoreDB.Collection("users").Where(path,equal,id).StreamAsync().Where((resp) => resp.Exists).Select((resp) => resp.Id).FirstOrDefault()

The error is

{
    "Grpc.Core.RpcException": [
        "Status(StatusCode=Unavailable, Detail=\"Transport closed\")"
    ]
}

and

{
    "Grpc.Core.RpcException": [
        "Status(StatusCode=Internal, Detail=\"GOAWAY received\")"
    ]
}

Seem like it not really about StreamAsync api but it is the first API that would be get called on my server
