GraphQL paging over related people for an organisation generates erro

[richardhallett]

When attempting to query related people and retrieve a cursor for pagination the query fails.

Example below

{
  organization(id: "https://ror.org/04qmmjx98") {
    id
    name
    country {
      name
    }

    people {
      edges {
        cursor
        node {
          id
        }
      }
    }
  }
}

Okay so in which case, the specific structure of this query causes an error, it generates a 500 on our side https://sentry.io/share/issue/51fdb3ca15f243b5843427f01df64f4d/

I think the user is handled then by your response in PID Forum but there is still an underlying issue here with the generated 500, unless im missing something the above query should be valid.

The correct way to do this is to obtain the (end-)cursor from a pageInfo object:

pageInfo {
        endCursor
        hasNextPage
      }

And then use the cursor with the after property.

people(after: "MQ")

This is specific to our graphql API? the docs generated on our API however suggest that its reasonable to return a cursor on edges that can then later be used i.e. like you said "after: "MQ"

Digging into this it looks like any connection should implement cursor_for_node Which would be used for the edge cursor
