Prisma

Is there a way to filter queries by where nodes _don’t_ have a specific type of related nodes?

<@U2Z3AS60H> yes! read this thread <https://github.com/graphcool/feature-requests/issues/110>

That works in the playground but Apollo complains about `Unexpected Name "null"`.

Ah... you need to use a variable instead of inlining `null` with Apollo

it's probably best if you use a variable for the whole filter

```
query items($filter: ItemFilter!) {
  allItems(filter: $filter) {
    id
  }
}
```

```
const variables = {filter: {parent: null}}
```

All right, thank you very much :slightly_smiling_face:
