invoking qscc contract function from another contract

[sami96h]

Im trying to retrieve transaction details using the GetTransactionByID function , but im getting this error => "Rejecting invoke of QSCC from another chaincode because of potential for deadlocks, original invocation for 'demo-contract'"

Here is the code : async GetAllResults(ctx, iterator) { let allResults = []; let res = { done: false, value: null };

    while (true) {
        res = await iterator.next();
        let jsonRes = {};
        if (res.value && res.value.value.toString()) {

            jsonRes.TxId = res.value.txId;
            const response= await ctx.stub.invokeChaincode('qscc',['GetTransactionByID',res.value.txId])
            jsonRes.test=response
            jsonRes.Timestamp = res.value.timestamp;
            jsonRes.Timestamp = new Date((res.value.timestamp.seconds.low * 1000));
            let ms = res.value.timestamp.nanos / 1000000;
            jsonRes.Timestamp.setMilliseconds(ms);
            if (res.value.is_delete) {
                jsonRes.IsDelete = res.value.is_delete.toString();
            } else {
                try {
                    jsonRes.Value = JSON.parse(res.value.value.toString('utf8'));

                } catch (err) {
                    console.log(err);
                    jsonRes.Value = res.value.value.toString('utf8');
                }
            }

            allResults.push(jsonRes);
        }
        if (res.done) {

            await iterator.close();
            return allResults;
        }

    }  
}

Issues related to Node chaincode should be addressed to the fabric-chaincode-node repository. However...

Cross chaincode calls to the qscc (and cscc) system chaincode do seem to be explicitly disallowed. Perhaps you will need to return the transaction IDs of interest from your smart contract, and then have the client separately evaluate the qscc chaincode's GetTransactionByID transaction function.
