Describe the bug

I wanted to setup payment for user to charge at future or setup subscription in future. I tried to create a checkout session doc like so:

			const checkoutSessionObject = {
				client: 'web',
				mode: 'setup',
				success_url: `${window.location.origin}/account/?setup_action=success`,
				cancel_url: `${window.location.origin}/account/?setup_action=cancel`,
				metadata: {
					email: user.email,
					uid: user.uid,
				},
			}

but i keep getting the following error: Error: missing required param line_items[0][currency].

To Reproduce

Steps to reproduce the behavior, please provide code snippets or a repository:

Expected behavior

I should be able to create a session to let users add payment method. without me charging them right away.
