HEEEELP Purche paid plan

Two weeks ago, I coded everything to allow users to buy a plan on a custom page… everything was working well since today.

This is the code:

import wixUsers from 'wix-users';
import wixPaidPlans from 'wix-paid-plans';

let planId = '4d845741-717a-43e5-a884-25ef3cbd3905';

$w.onReady(function () {
 
$w('#buyNow').onClick((event) => {

    let user = wixUsers.currentUser;
    let isLoggedIn = user.loggedIn;
    if (!isLoggedIn) {
      wixUsers.promptLogin().then(() => {
        wixPaidPlans.purchasePlan(planId)
        .then((myPurchase) => {
            let myOrderId = myPurchase.orderId;
            let myWixPayOrderId = myPurchase.wixPayOrderId;
            let myWixPayStatus = myPurchase.wixPayStatus;
          })
      })
    } else {
        wixPaidPlans.purchasePlan(planId)
        .then((myPurchase) => {
        let myOrderId = myPurchase.orderId;
        let myWixPayOrderId = myPurchase.wixPayOrderId;
        let myWixPayStatus = myPurchase.wixPayStatus;
    }
 )}

})
})

When testing the code on preview, this message appears… without any clue of how to solve it

Please give me a hand friends
