无法在Hyperledger Fabric Chaincode上的GetQueryResult（queryString）之后立即调用GetState

Question

On my Fabric Golang chaincode, I need to find a list of object, then loop and call getState() on other objects on the ledger. It work with GetStateByRange(), but not with GetQueryResult(). All those are from shim.ChaincodeStubInterface

With GetQueryResult() I get a "No revision tag detected" after every getState()

Examples:

This works!

func (s *SmartContract) queryAllFormations(APIstub shim.ChaincodeStubInterface, args []string) sc.Response {

                resultsIterator, _ := APIstub.GetStateByRange("FORM_1","FORM_99")
                for resultsIterator.HasNext() {
                    var formation Formation
                    json.Unmarshal(formationAsBytes.Value, &formation)
                    formationAsBytes, _:= resultsIterator.Next()
                    // Will succeed !
                    personAsBytes, _:= APIstub.GetState(formation.PersonID)
                    [...]
                 }
                 resultsIterator.Close()

This will fail!

func (s *SmartContract) queryAllFormations(APIstub shim.ChaincodeStubInterface, args []string) sc.Response {
            queryString := ...
            resultsIterator, _ := APIstub.GetQueryResult(queryString)
            for resultsIterator.HasNext() {
                formationAsBytes, _:= resultsIterator.Next()
                var formation Formation
                json.Unmarshal(formationAsBytes.Value, &formation)
                // WILL fail
                personAsBytes, _:= APIstub.GetState(formation.PersonID)
                [...]
            }
            resultsIterator.Close()

error: [client-utils.js]: sendPeersProposal - Promise is rejected: Error: GET_STATE failed: transaction ID: 2117b32cc69873be0e752eb644250c4156f29d9ec48d385f88d43ca1705b909d: No revision tag detected at /home/apa/DEV/rinku/rinku-server/node_modules/fabric-client/lib/Peer.js:114:16 at /home/apa/DEV/rinku/rinku-server/node_modules/fabric-client/node_modules/grpc/src/client.js:586:7

Any idea ? Thanks in advance
