Stripe Issue on Local Install

[aklusa022]

Hello,
When having the createCustomerOnSignUp option set to true in auth.ts stripe config like so

createCustomerOnSignUp: true

within auth.ts

export const createAuth = (
    ctx: GenericCtx<DataModel>,
    { optionsOnly } = { optionsOnly: false },
) => {
    return betterAuth({

        trustedOrigins: ["http://localhost:3000"],
        plugins: [
            // The Convex plugin is required for Convex compatibility

            convex(),
            stripe({
                createCustomerOnSignUp: true,
                stripeClient: stripeClient,
                stripeWebhookSecret: "whsec_mywhsecretconfg"

            }),

        ],
    });
};

The console (bunx run dev)

Again this is on local install to circumvent the convex+better auth plugin restrictions.

Thanks
