Error: Retried job not failed

[ghost]

export const consume = async () => {
	const worker = new Worker(
		"contacts",
		async (job: Job) => {
			await sleep(200);
			throw new Error("foobar");
		},
		{
			connection: redisConnection,
			limiter: {
				max: 20,
				duration: 1000,
			},
			concurrency: 10,
		}
	);
	worker.on("completed", async (job: Job) => {
		console.log("[completed]", job.data.email);
	});
	const failedJobs: Job[] = [];
	worker.on("failed", async (job: Job) => {
		console.log("[failed]", job.stacktrace);
		failedJobs.push(job);
	});
	worker.on("drained", async () => {
		console.log("[queue drained]");
		await worker.close();

       // I have to do this because defaultJobOptions.removeOnFail: false, doesn't work, already have opened issue
		failedJobs.forEach(async (job) => {
			await job.retry("failed");
		});
	});
};

If I run this multiple times, this is logged

UnhandledPromiseRejectionWarning: Error: Retried job not failed

(node:2403) UnhandledPromiseRejectionWarning: Unhandled promise rejection. This error originated either by throwing inside of an async function without a catch block, or by rejecting a promise which was not handled with .catch().

Why is this happening?
