I'm running some testings of Stripe code in my TypeScript MicroService :
process.env.STRIPE_KEY = 'sk_test_...............';
import Stripe from 'stripe';
export const stripe = new Stripe(process.env.STRIPE_KEY!, {
apiVersion: '2020-03-02',
});
However I keep getting that the constructor is not defined :
**TypeError: stripe_1.default is not a constructor**
1 | import Stripe from 'stripe';
> 2 | export const stripe = new Stripe(process.env.STRIPE_KEY!, {
| ^
3 | apiVersion: '2020-03-02',
4 | });

Any idea what might cause this ?
