Hi team, I was testing Apple Pay payments and I am thrown this error when trying to pay for a product with Apple Pay. 

Here is a clear text error I got when trying to do a regular checkout but paying with Apple Pay at the end: 

"

Bad Request

The operation cannot be completed:

• Create/update: a mandatory field is not set.
• Delete: another model requires the record being deleted. If possible, archive it instead.

Model: Event Registration (event. registration)

Field: Event (event id)

"

Here is the error I used when trying to use Express Checkout Apple Pay: 

"

Internal server error

null value in column "event_id" of relation "event_registration" violates not-null constraint
