failed to initialize plugins server: unable to parse additional clusters config

[bobdivx]

Summary
Issue with Kubeapps APIs deployment: "failed to initialize plugins server: unable to parse additional clusters config".

Background and rationale
I am attempting to deploy Kubeapps within the monitoring namespace of my Kubernetes cluster. My use case involves enabling multi-cluster support and utilizing Kubeapps for managing Helm charts and other Kubernetes resources. Despite configuring the necessary deployments, services, and ConfigMaps, the kubeapps-apis pod fails to initialize properly, which is critical for interacting with Kubernetes clusters through Kubeapps.

Description
The kubeapps-apis pod enters a CrashLoopBackOff state. The logs provide the following error:

Error: failed to initialize plugins server: unable to parse additional clusters config: invalid character 'c' looking for beginning of value

The clusters-config.yaml ConfigMap contains the following configuration:

clusters:
  - name: default
    apiServiceURL: https://kubernetes.default.svc
    serviceToken: /var/run/secrets/kubernetes.io/serviceaccount/token
    caCert: /var/run/secrets/kubernetes.io/serviceaccount/ca.crt

I have attached my YAML configuration below:

ConfigMaps

# ConfigMap for clusters-config
apiVersion: v1
kind: ConfigMap
metadata:
  name: kubeapps-clusters-config
  namespace: monitoring
data:
  clusters-config.yaml: |
    clusters:
      - name: default
        apiServiceURL: https://kubernetes.default.svc
        serviceToken: /var/run/secrets/kubernetes.io/serviceaccount/token
        caCert: /var/run/secrets/kubernetes.io/serviceaccount/ca.crt

# ConfigMap for plugins-config
apiVersion: v1
kind: ConfigMap

  name: kubeapps-plugins-config
  namespace: monitoring
data:
  plugin-config.yaml: |
    plugins:
      - name: helm
        version: v1alpha1

Despite this setup, I encounter persistent issues with the kubeapps-apis pod initialization.

Additional context
I suspect the issue may relate to the parsing of the clusters-config.yaml file, given the logs mention an "invalid character 'c'". Any guidance on resolving this error or insights into potential misconfigurations in my YAML files would be greatly appreciated.

Thank you for your assistance!
