checkout breaks when Paystack is the only payment provider

[nathaniel1616]

I am using medusa-paystack plugin at medusa.
https://medusajs.com/plugins/medusa-payment-paystack

Checkout page works fine when there are two payment provider.
When I select , paystack only as the only payment provider , I get this error at the backend

error: Error from Paystack API with status code 400: Invalid Email Address Passed
Error: Error from Paystack API with status code 400: Invalid Email Address Passed

at step (C:\Users\nat\medusa\my-medusa-store\node_modules\medusa-payment-paystack\dist\lib\paystack.js:33:23)

I found a similar issue solved on Stripe on issue here #261

I would like to see an implementation with paystack.

I don't know the specifics of your setup, but it looks like you're trying to initiate a Paystack payment when there's no email address available yet.

The solution will be similar to my Stripe example you mentioned.

When you have only one payment provider active, Medusa will select it by default when you check out. Make sure you're not trying to initiate e.g. PaystackPop.setup before the customer email and order amount are available. You might want to add specific conditions to the checkout flow to fit your use case.
