Lighthouse: null return not being allowed

[souljacker]

My schema has

type Query {
  me: User
}

And my me resolver is returning null if the user is not logging it. But I get this error

debugMessage: Cannot return null for non-nullable field User.id.

Shouldn't I be allowed to return null in this case?

I was able to circumvent this by creating a a custom type and returning it instead

type Query {    
    me: mePayload
}

type mePayload {
    user: User
}

This allows me to return null

Can you show us your User model type?

type User @model {
    id: ID! <--- is the reason probably
}

[joskfg]

Are you returning null or are you returning a user without data?

[spawnia]

I think the issue you are having is a combination of what @eriktisme and @joskfg said.

Make sure to return null from the me field, not an empty User.

Closing as this looks like expected behaviour.
