To Reproduce simply you just need to pay using the payment link, note that the user is registered on the website before going to do the payment.

@arnav13081994 thank you.

I have seen this error when local and remote database do not match, after some reset/restore of local djstripe database. What happened in my case was that

1. a User is created and associated with a Customer
2. Customer records the ID of the User when it is synced to stripe.com
3. When local database is re-created, User gets another id.
4. When Customer is used, it tries to locate the User with the saved id, and an error occurs when the user with that id does not exist or points to another Customer.
