Cannot read property 'toString' of undefined

[lastmjs]

This query fails:

query {
  findCalls(filter: {
    id: {
      eq: 150
    }
  }) {
    items {
      id
      company {
        id
        name
        users {
          user {
            email
            is_active
          }
        }
      }
    }
  }
}

Here is the result:

  "data": {

          "id": "150",
          "company": null
        }
      ]
    }
  }
}

When I add id to the selection set of users.user, the query succeeds:

query {
  findCalls(filter: {
    id: {
      eq: 150
    }
  }) {
    items {
      id
      company {
        id
        name
        users {
          user {
            id
            email
            is_active
          }
        }
      }
    }
  }
}

Companies and users have a many-to-many relationship, so there is a join table called Companies_users that looks like this:

type Companies_users {
    id: ID! # Note that this id exists in the schema because it is necessary, but my database actually does not have this field. Not usre if that matters in this case
    company: Companies!
    user: Users!
}

This looks like it is related to #1752?

This only happens in 0.16.0-alpha3 after #1834. #1861 should fix this issue!

@lastmjs we dropped 0.16.0-alpha4 to take care of this issue. Mind checking and see it fixes the issue for your. Feel free to re-open if it's not the case.
