This is due to a change we did for performance improvement in GraphQL. Previously, we would be selecting entire rows, no matter now many fields you wanted from a table. Now, we are only selecting exactly what you ask for. However, if you ask for nothing, you get nothing. Therefore, you cannot have join-only fields in the schema, such as here: taxAndAccountingGroup { items { joindown_TaxAndAccountingInformation_via_TaxAndAccGroup { items { joinup_TaxCode_via_TaxCodeSales { joinup_Vat { rate } } } } As you figured it out, it works, if you add at least one field. But you did that do that with joinup_TaxCode_via_TaxCodeSales. Here is a query that works: query GetTaxAndAccountGroups($cid: Int!) { useCompany(no : $cid) { taxAndAccountingGroup { totalCount items { taxAndAccountingGroupNo description joindown_TaxAndAccountingInformation_via_TaxAndAccGroup { totalCount items { taxAndAccountingGroup description joinup_TaxCode_via_TaxCodeSales { taxCode joinup_Vat { rate } } } } } } } } Result: { "data": { "useCompany": { "taxAndAccountingInformation": { "totalCount": 8, "items": [ { "taxAndAccountingGroup": 1, "description": "Avgiftspliktig høy sats", "joinup_TaxCode_via_TaxCodeSales": { "taxCode": 3, "description": "Utgående MVA - høy sats", "joinup_Vat": { "rate": 25 } } }, { "taxAndAccountingGroup": 2, "description": "Avgiftsfritt", "joinup_TaxCode_via_TaxCodeSales": { "taxCode": 4, "description": "Avgiftsfritt salg innland", "joinup_Vat": null } }, ...
