I am generating stripe checkout url from trpc endpoint and want to redirect user to that page. Here is what I am doing right now ```export const purchaseRouter = createTRPCRouter({ getUrl: publicProcedure .input(z.object({ text: z.string() })) .query(async ({ input, ctx }) => { const host = ctx.req.headers.host; if (!host) { throw new Error("No host"); } const session = await stripe.checkout.sessions.create({ line_items: [ { price: "price_1N7vQ8CxIhQOHpG7clowFgAm", quantity: 1, }, ], mode: "payment", success_url: `https://${host}/?success=true`, cancel_url: `https://${host}/?canceled=true`, }); ctx.res.redirect(303, session.url); }), });```
