Angular deserialization of ushort array sent with signalR messagepack

I have an asp.net server that sends data as ushort[] to clients via signalR messagepack. When listening for that data on my angular client using this code:

this.hub.addListener('SendImage', (data: Uint16Array ) => {
console.log(data instanceof Uint16Array);
...
}

// and the signalr builder
this.hubConnection = new HubConnectionBuilder()
.withUrl(`${this.configService.apiBaseUrl}/signalRHub`)
.withAutomaticReconnect([0, 1000, 10000, 30000])
.withHubProtocol(new MessagePackHubProtocol())
.build();


it seems like the data is not deserialized as Uint16Array. The console logs false. If the server sends the data as byte[] instead and my client side receives the data as Uint8Array then its fine. Im using the default Add

Is it possible to directly receive the data as Uint16Array?
