I'm using DataDog on Mac with the Agent installed. I have verified that the Agent is running fine and that my ENV vars are correct. I wrote the following script to send logs to local files and to the DataDog server:

const { format, transports, createLogger } = require("winston");
const DatadogWinston = require("datadog-winston");

logDir = 'logs'

const logger = createLogger({
    level: 'info',
    format: format.combine(format.timestamp(), format.json()),
    transports: [
        new transports.File({ filename: `${logDir}/error.log`, level: 'error' }),
        new transports.File({ filename: `${logDir}/warn.log`, level: 'warn' }),
        new transports.File({ filename: `${logDir}/info.log`, level: 'info' }),
    ],
});

if (process.env.LIVE_LOGGING == "yes") {
    logger.add(new DatadogWinston({
        apiKey: process.env.DATADOG_API_KEY,
        hostname: process.env.DATADOG_HOSTNAME,
        service: 'orch-backend',
        ddsource: 'nodejs'
    }));
}

logger.info('Yo!', new Error("something went wrong!"));

Now, I can see logs in my local file but the DataDog dashboard is empty. Any idea what I might be doing wrong?
