SDK Send Events not working or erroring

[Skeletor11]

OS and version used: Windows 11
Node.js version: 22.11.0, Deno v2.0.6
npm version: 10.9.0
list of installed packages: N/A
Version: Deno 2.0.6

When using the Node SDK in Deno to attempt to sent events and batch events to the cloud, my callback function is not getting called, no error is thrown and no messages are going through. Example code below:

import { Client, Message} from 'npm:azure-iot-device@1.18.3';
import { clientFromConnectionString } from 'npm:azure-iot-device-http';
import '@std/dotenv/load';

const deviceConnectionString: string = Deno.env.get('IOTHUB_DEVICE_CONNECTION_STRING')!;

const { DeviceID, HostName, SharedAccessKey } = parseConnectionString(
deviceConnectionString,
);
const client: Client = clientFromConnectionString(deviceConnectionString);

try {
client.sendEvent(new Message('some data from my device'), printResultFor("send"));
} catch (error) {
console.log(error);
}

function printResultFor(op: any): (err: any, res: any) => void {
return function printResult(err: any, res: any): void {
try {
if (err) console.log('Failed to send message with status ' + op + ' error: ' + err.toString());
if (res) console.log('completed batch SDK ' + op + ' status: ' + res.transportObj.statusCode + ' ' + res.transportObj.statusMessage);
} catch (error) {
console.log(error);
}
};
}

Apologies if you are already, but are you opening a transport connection (await client.open()) before you're calling client.SendEvent()?
