while running the query.js. I have following active docker running Before running the node query.js, when i am running npm install its giving following warning : npm WARN [email protected] No repository field. Is this the problem. Can any one please help me out about where it is going wrong.

Answer 1

I have met the same error during run sample, it failed to connect. I fixed it with following steps:

1. get machine IP address with: ifconfig
2. replace localhosts in query.js with IP in #1

Addition to Angela's answer:

To anyone having this issue and using Docker Toolbox, do docker-machine ls and copy the IP adress at the URL column of your ACTIVE machine and paste the IP adress to every localhost in both query.js and invoke.js files.
