Can anyone please help me with demo?

On main page in a red info block I am seeing message "There was an error starting the demo. Please try again. Ensure you delete both the demo and the blockchain service Identity or token does not match."

In this case, it is best to remove all instances of the application and service and then redeploy.

If you have a file based keystore and running the app on bluemix, the keystore data is lost after application is restarted or redeployed as file system is not persistent.

I have forked this project and made changes to use Cloudant based KeyStore. You can refer to the code here: https://github.com/sachinjha/car-lease-demo-1486642013191.

@Vovchikus I am facing the same issue. Have you resolved this? If so, how? Thanks

Hi Adam, The way to solve it is to provide a different implementation of KeyStore. In the forked project - https://github.com/sachinjha/car-lease-demo-1486642013191 , you will find CloudantKeyStore file. During application startup , when chain is initialized an instance of this keystore implementation is provided instead of file based keystore. You could use any db. I chose cloudant cause it had a free plan.
