Not able to configure gcp to impersonate service account

[vikas-cd]

I have been trying to impersonate a service account to access gcp resources, but not able to achieve, pls help !

This is how my gcp.spc looks like :

connection "gcp" {
plugin = "gcp"
project = "project-01-418720"
credentials = "~/.config/gcloud/application_default_credentials.json"
impersonate_service_account = "cdai-scan-servacc-180692@project-01-418720.iam.gserviceaccount.com"
}
