Description of problem:

Accessing any of the Topology, CI, or Kubernetes tab ends with an error.

```
Request failed with 500 Internal Server Error,

{"error":"ENOENT: no such file or directory, open '/var/run/secrets/kubernetes.io/serviceaccount/token'"}

```

I believe that same configuration was working fine in 1.2.

Prerequisites (if any, like setup, operators/versions):

OCP 4.16 (clusterbot provisioned ROSA cluster)
DH operator 1.3.

Steps to Reproduce

1. Plugin configuration
   ```

• disabled: false
  package: ./dynamic-plugins/dist/backstage-plugin-kubernetes-backend-dynamic
  pluginConfig:
  kubernetes:
  clusterLocatorMethods:
• clusters:
• authProvider: serviceAccount
  customResources:

  apiVersion: v1alpha1
  plural: rollouts

  group: route.openshift.io
  plural: routes
• apiVersion: v1
  group: tekton.dev
  plural: pipelineruns
• apiVersion: v1
  group: tekton.dev

  name: cluster
  serviceAccountToken: ${K8S_SERVICEACCOUNT_TOKEN}
  skipMetricsLookup: true
  skipTLSVerify: true
  url: https://kubernetes.default.svc
  type: config
  serviceLocatorMethod:
  type: multiTenant
  ```

Actual results:

The pod is throwing an error when accessing resources.

Expected results:

Resources are displayed in the UI.
