Received RpcError is always code 2: Incomplete response

[WindFreaker]

Hi, I am struggling to send error information from my Tonic gRPC server to my gRPC web client. Every time I receive an RpcError on the client, it always comes out as code 2 with the message "Incomplete response".

Here is a snippet of my client code (in case I am doing anything glaringly wrong):

client.beginRegistration(request, {}, async (err, response) => {

	if (err) {
		console.log(`Error: ${err.message}`);
	}

	...

}

However when I inspect the network information for the request, I see headers that contain my error information.
