Help with Stripe payments

Hi I have a problem with Stripe. I have test mode on, and when completing a payment with the test card (4242), payment is successful but on my DB looks like "incomplete" instead of "trialing", does anyone know why? This is my code implementation: async function handlePlanClick(planId: string) { try { setLoading(planId); const result = await authClient.subscription.upgrade({ plan: planId, successUrl: ${process.env.NEXT_PUBLIC_URL}/dashboard, cancelUrl: ${process.env.NEXT_PUBLIC_URL}/dashboard/plans, annual: billingCycle === "yearly", }); if (result.error) { console.error('Subscription error:', result.error); return; } } catch (error) { console.error('Error upgrading subscription:', error); } finally { setLoading(null); } } 2. Also I have another doubt, but not my main concern since I think I already got an idea but any help would be appreciated. Basically if anyone clicks on a plan, gets redirected to checkout, but if he cancels for example, I already have a row on my DB with a reference ID created and marked as incomplete, now if that same user tries to click again on "upgrade plan"; nothing happens and a error 500 pops because my referenceID is UNIQUE. (as i said i think i got a solution for this but i bet you are way smarter and better coder than me, so any help is appreciated) Thank you a lot guys, hoping any1 can help!
