Bluemix IoT Foundation Starter give Error: Lost connection to server

I am trying the Internet of Things Foundation Starter boilerplate in Bluemix. Here are the steps I am following:

  1. Create a new app using the boilerplate
  2. Once the app is up, I go to the URL and see the NodeRED home page
  3. I click on the button to take me to the NodeRED editor
  4. In another browser window I have the IoT Sensor available here: https://quickstart.internetofthings.ibmcloud.com/iotsensor/ up and running
  5. I configure the "IoT App In Node" with the address of my IoT sensor. I have removed the ":"'s and have made the letters lowercase.
    1. When I click Deploy in the NodeRED editor, I see the following error: "Error: Lost connection to server"

After step 2 I already see these errors in the log:

After step 5 after the error happens, I see the following error:

Now if I restart the app everything just works fine. But I can recreate the above scenario consistently every time with these steps:

  1. create new app from boilerplate
  2. go to NodeRED editor
  3. configure IoT in-node
  4. deploy
  5. get error
  6. stop and start runtime
  7. all works

Need help figuring out why this is happening and how to prevent it.

Thanks

    A permanent fix has been uploaded in the npmjs and Internet of Things Foundation Starter boilerplate of Bluemix, which resolves this issue.
