Is this a BUG REPORT or FEATURE REQUEST?:

Uncomment only one, leave it on its own line:

/kind feature

What happened:

We use the service account token parameter to deploy to Kubernetes within our CI/CD process. This works in 0.9.1 but regressed in 0.9.2.

What you expected to happen:
We expected that the token worked and authorized the CI/CD container to deploy the service.

How to reproduce it (as minimally and precisely as possible):
ks apply $env --token=
