Can't access link properties on computed backlinks

[nathanburgess]

Code

const query = e.params(
  {
    parentId: e.uuid,
  },
  (params) =>
    e.select(e.Child, (child) => ({
      filter_single: e.op(params.parentId, "in", child.parents.id),
      parents: (parent) => ({
        "@prop": true,
        filter_single: e.op(parent.id, "=", params.parentId),
      }),
    })),
);

Schema

module default {
  type Child {
    multi link parents := .<children[is xlb::Parent];
  }

  type Parent {
    mutli link children: Child {
      prop: str;
    }
  }
}

Generated EdgeQL

This query causes the builder to throw an error, it's not possible to call .toEdgeQL
