Getting an error when trying to instantiate chaincode - hyperledger-fabric

Question

I'm getting the following error when trying to instantiate my chaincode. Im just trying to instantiate the fabcar chaincode on a peer running in kubernetes.
kubectl exec -n blockchain $PEER_POD -- bash -c 'CORE_PEER_MSPCONFIGPATH=$ADMIN_MSP_PATH peer chaincode instantiate -o ord1-hlf-ord.blockchain.svc.cluster.local:7050 -C mychannel -n mycc -l node -v 1.0 -c '{"Args":[""]}''
This then gives me the following error:
Error: chaincode argument error: invalid character 'A' looking for beginning of object key string
I think it has something to do with passing the constructor arguments with the command ('{"Args":[""]}') but I compare these to the command used in the startFabric.sh script and its the same format:
docker exec -e "CORE_PEER_LOCALMSPID=Org1MSP" -e "CORE_PEER_MSPCONFIGPATH=/opt/gopath/src/github.com/hyperledger/fabric/peer/crypto/peerOrganizations/org1.example.com/users/Admin#org1.example.com/msp" cli peer chaincode instantiate -o orderer.example.com:7050 -C mychannel -n fabcar -l "$LANGUAGE" -v 1.0 -c '{"Args":[""]}' -P "OR ('Org1MSP.member','Org2MSP.member')"
Scratching my head with this one, so would really appreciate if someone knew what the problem could be...
Fabric v1.2
Logs:
