```

this is my SDL:

```type Query {
ok: Boolean!
}

type Mutation {
signup(referralCode: String, firstName: String!, lastName: String!, email: String!, password: String!): String
}
```

A few days ago, everything was working fine until I switched to NexsusJS framework for my backend.

I tried apollo client, I tried `urql`, but both have a problem parsing node type document.

this is `TypeError: graphql.print is not a function` urql for example

any ideas what I'm doing wrong?
