Issues with using BGD and manual scaling down

[Shrinidhi2Mee]

I use cloud foundry to deploy my code using IBM’s Bluemix. I wish to manually manage scaling up and scaling down of instances of an application. I have an external script running to manage this process.

I'm unable to perform BGD.I have started facing problem from the time this manual scaling was integrated.

Command used:
bx cf bgd <app_name> -f ./<file_name>.yml

ISSUE:

There is no issue with the port number as captured in the error. It is given as environment variable.

Note:
Push works without any issue.
bx cf push <app_name> -f ./<file_name>.yml

It would be great if you could help me sort this out!

• name: <app_name>

  disk_quota: 1G

  host: <app_name>
