Hi guys,
I've successfully install GoCD through helm. The sample pipeline is
successfully built using Kubernetes Elastic Agent.
While I was adding a new pipeline, I needed to be added SSH keys to GoCD
server, and elastic profile agent according to the documentation
https://github.com/gocd/kubernetes-elastic-agents
But, probably the syntax of YAML format for Pod was wrong. I've got an
error in the logs

After removing *volumeMounts* I still got the error.
I've removed volumeMounts in profile
- /go/admin/elastic_profiles
- double checked in cruise-config.xml,
- restart GoCD server Pod
but still there is an issue.
Should I've reset cache, if there is one or do something else to apply the
changes?
*Stack:*
GoCD *19.7.0*
Kubernetes Elastic Agent Plugin *3.0.0-156*
