For those having the same issue despite setting up the Apple Pay certificate in the Stripe dashboard, you need to ensure that your StripeProvider
has stripeAccountId
set. You can find this in your account settings. I initially had this missing, which caused this error to occur.
<StripeProvider
// -- THIS WAS MISSING! --
stripeAccountId={...}
// --
publishableKey={...}
merchantIdentifier={...}
urlScheme={...}
>
...
</StripeProvider>
