[Python] In strawberry, how do I make a strawberry.input non-nullable but optional in an...

I have two fields in an input:

@strawberry.input
class UserUpdateInput:
name: str | None = strawberry.UNSET
description: str | None = strawberry.UNSET


name - in the backend database - is not nullable. description is nullable.

Above is almost what I need:

• The fields are optional in a mutation.
• They are strawberry.UNSET when not specified.
• Description can be set to None, or any string.

But now name can also be set to None which is wrong. But taking out the None type-hint (i.e name: str = strawberry.UNSET) makes name no longer optional.

In GraphQL I'd like (something like) this:

mutation Update {
updateUser(id:1, userUpdateInput: {name:"tom",description:"too old for this s..."}) {
id
}
}


or this:

mutation Update {
updateUser(id:1, userUpdateInput: {description:null}) {
id
}
}


but not:

mutation Update {
updateUser(id:1, userUpdateInput: {name:null}) {
id
}
}


Is there a way to specify both optional and non-nullable in strawberry's schema?
