Helmfile - No Current Context

Using Helmfile in Gitlab, since upgrading to latest ci template version I get the following error message:

$ setup_kubeconfig
[INFO] --- using KUBECONFIG provided by GitLab
[INFO] --- switch to the given KUBE_CONTEXT: infrastructure/kubernetes:staging
$ setup_pgp_key
$ set_default_namespace
$ helmfile_deploy
[INFO] --- deploy
[INFO] --- $kube_namespace: redis
[INFO] --- $environment_type: staging (passed as helmfile environment)
[INFO] --- $environment_name: redis-staging
[INFO] --- $environment_hostname: shared-services-redis-staging.
error: no current context is set

Any suggestions?
