i am new to hyperledger & trying to modify existing balance transfer example in fabric sample. Here change i am doing is changing the name & domain of orderer & peers in **cryptogen.yaml** file. Also made changes accordingly in configtx.yaml & docker-compose.yaml files. Here is the change in cryptogen.yaml file : 

```
OrdererOrgs:
  - Name: Orderer
    Domain: say.com

    Specs:
      - Hostname: orderer

PeerOrgs:
  - Name: Customer1
    Domain: customer1.say.com
    CA:
       Hostname: ca

    Template:
      Count: 2
      SANS:
        - "localhost"

    Users:
      Count: 1

  - Name: Customer2
    Domain: customer2.say.com
    CA:
       Hostname: ca

    Template:
      Count: 2
      SANS:
        - "localhost"
    Users:
      Count: 1

```

Here is configtx.yaml file :

```

I am able to generate crypto materials using cryptogen tool & container is getting up. Using **docker ps** i can see all the containers. At the time of enrolling user getting following error : 

> 
> [DEBUG] Helper - [FileKeyValueStore.js]: FileKeyValueStore.js -
>  constructor [ERROR] Helper - Failed to get registered user: Jim,
>  error: TypeError: Cannot read property 'setStateStore' of undefined
>  at hfc.newDefaultKeyValueStore.then (/home/ubuntu/fabric-samples/balance-transfer/app/helper.js:208:9)
> 
>

Please let me know what is the reason i am getting this issue.
