I'm getting this error trying to deploy a card to a working blockchain on cloud, any idea? Thanks in advance. I'm using a mac, following the guide (Kubernetes installed/configured well, I think):

<https://ibm-blockchain.github.io/interacting/>

```
./create/create_composer-rest-server.sh --paid --business-network-card /Users/sm/jsblock/tutorial-network/PeerAdmin@fabric-network.card
Configured to setup a paid storage on ibm-cs
