I am trying to integrate PayPal subscription into my React app. I've run through the docs at https://developer.paypal.com/docs/subscriptions/integrate/ . I created a product and a plan. That seems to be fine. I've installed the react-paypal-button-v2 and added my button: ``` <PayPalButton options={{ vault: true, clientId: "sb", currency: "USD" }} createSubscription={(data, actions) => { return actions.subscription.create({ plan_id: 'P-#######xxxxxxxxx' }); }} onApprove={(data, actions) => { // Capture the funds from the transaction return actions.subscription.get().then(function (details) { // Show a success message to your buyer alert("Subscription completed"); // OPTIONAL: Call your server to save the subscription return fetch("/paypal-subscription-complete", { method: "post", body: JSON.stringify({ orderID: data.orderID, subscriptionID: data.subscriptionID }) }); }); }} /> ``` But I get an error immediately after I click any of the buttons that appear on the screen. The first error that I see is: POST https://www.sandbox.paypal.com/v1/billing/subscriptions 404 (Not Found) Am I missing something? Is the library just broke? I'm not sure how to really debug this at this point. Thanks
