Create a new project, create a new route and add this code:

const someLongRunningOperation = async () => {
	return new Promise((resolve) => {
		setTimeout(() => {
			resolve('done');
		}, 10000);
	});
};

router.post('/', async (c) => {
	c.waitUntil(async () => {
		await someLongRunningOperation();
	});
	return c.json({ success: true });
});

error
