hi! that means you're using the wrong public key pk_test_xxx on the frontend basically.
like you create the CheckoutSession on the backend using the secret key of one Stripe account, but are using the publishable key of a different Stripe account on the frontend. You should carefully check you're using the same pair of keys from https://dashboard.stripe.com/apikeys
