Hi guys! Having these relations (a customer have N contracts and N billingAccounts), my prisma client generate a createCustomer mutation. But is possible to create only customer entity? In the mutation is requesting the relations as non nullable types..

I guess this is due to your datamodel. Can you share it?

Here you have <https://github.com/prisma/prisma/issues/4095> (it's the same datamodel), It has a bug (doesn't create arrays), explained on the issue.

So then this is simply a bug in the introspection. The generated datamodel specifies that a customer must have exactly 1 account and contract. Therefore the API is forcing you to specify this parameter.

So your datamodel is something like this:
```
type Customer {
  accounts: Account!
}
```
Instead it should be:
```
type Customer {
  accounts: [Account]
}
```
Then that problem will be gone.

Right <@U3H00EB8T>, I have modified it by hand and all it's ok!
