Helm command failure: Kubernetes cluster unreachable: context does not exist

[satishweb]

What happened?

devspace dev command failed with below error:

$ devspace dev
info Using namespace 'devspace-myname'
info Using kube context 'my-aws-k8s-context-name'
deploy:dev Deploying chart  (devspace-myname) with helm...
create_deployments: error deploying dev: unable to deploy helm chart:  error executing 'helm upgrade devspace-myname --values /tmp/38929297 --install --namespace devspace-myname /path/to/my/chart/ --kube-context my-aws-k8s-context-name': Error: Kubernetes cluster unreachable: context "my-aws-k8s-context-name" does not exist
fatal exit status 1

What did you expect to happen instead?
devspace dev successfully executing helm command to install the helm chart

How can we reproduce the bug? (as minimally and precisely as possible)

1. Copy this devspace.yaml into your project
2. Run command devspace dev

My devspace.yaml:

Anything else we need to know?
Apparently, failure was caused by use of HOME var declaration. Renaming HOME to CONTAINER_HOME solved the problem.

It took a while to figure out the root cause. If --debug flag was passed to the helm command, it would have been more easier to find the root cause.

Closing in favor of https://github.com/devspace-sh/devspace/issues/2846

[satishweb]

Root cause: HOME variable was declared in the devspace.yaml and that caused changes to the devspace runtime environment. Removing HOME variable resolved the error

If the debug flag was passed to the helm command, this root cause could have been clearer. #2846 is added for this feature request.
