Target uri should not have null authority

Hi there,

Been trying to create a simple client/server from one protobuf file. The server works as expected, but when I am trying to configure the client

pekko.grpc.client {
  "prime.PrimeNumberService" {
    host = "127.0.0.1"
    port = 9000
    use-tls = false
  }
}

I get the following error:

[IllegalArgumentException: requirement failed: target uri should not have null authority, got [http://///127.0.0.1:9000]]

And some more details:

@PekkoGrpcGenerated
28object PrimeNumberServiceClient {
29  def apply(settings: GrpcClientSettings)(implicit sys: ClassicActorSystemProvider): PrimeNumberServiceClient =
30    new DefaultPrimeNumberServiceClient(GrpcChannel(settings), isChannelOwned = true)
31
32
33  def apply(channel: GrpcChannel)(implicit sys: ClassicActorSystemProvider): PrimeNumberServiceClient =
34    new DefaultPrimeNumberServiceClient(channel, isChannelOwned = false)

Do you know if I made a typo in the configuration or should I use a different approach?

Thanks!

Start by reproducing the client setup from the pekko.grpc.client configuration block with host 127.0.0.1, port 9000, and use-tls = false. Follow the generated PrimeNumberServiceClient entry point and the resulting target URI error. Done means the simple client can connect without the null-authority IllegalArgumentException.
