Kubernetes platform (e.g. Google Kubernetes Engine)

Standard Kubernetes installed manually.

Describe the bug
When installing fission in the fission namespace, everything works. But when installing it in another namespace, the fission check command fails event though I can create and test functions properly:

$ fission check
fission-services
--------------------
× failed to get executor deployment status
× failed to get router deployment status
× failed to get storagesvc deployment status
Error: Error found: failed to get webhook deployment status
× failed to get webhook deployment status

fission-version
--------------------
√ fission is up-to-date

Event though the deployments are ok:

$ kubectl get deployments
NAME             READY   UP-TO-DATE   AVAILABLE   AGE
buildermgr       1/1     1            1           4m16s
executor         1/1     1            1           4m16s
kubewatcher      1/1     1            1           4m16s
mqtrigger-keda   1/1     1            1           4m16s
router           1/1     1            1           4m16s
storagesvc       1/1     1            1           4m16s
timer            1/1     1            1           4m16s
webhook          1/1     1            1           4m16s

Using fission check -n does not fix the issue.

To Reproduce

Install Fission 1.20.1 with this values.yaml:

builderNamespace: mynamespace
functionNamespace: mynamespace
defaultNamespace: mynamespace

Expected result
Fission should be installed and fission check should return that everything is okay.

Actual result
As shown above, the deployments are OK but fission check fails.
