Steps to reproduce

1. Install k8sgpt-operator via helm.
2. Create a secret for google gemini with apikey.
3. Use google as a backend and model as stated in below YAML.

apiVersion: core.k8sgpt.ai/v1alpha1
kind: K8sGPT
metadata:
  name: k8sgpt-sample
  namespace: k8sgpt-operator-system
spec:
  ai:
    enabled: true
    model: gemini-2.0-flash
    backend: google
    secret:
      name: k8sgpt-sample-secret
      key: gemini-api-key
    # anonymized: false
    # language: english
  noCache: false
  version: v0.3.41
  # filters:
  #   - Ingress
  # sink:
  #   type: slack
  #   webhook: <webhook-url>
  # extraOptions:
  #   backstage:
  #     enabled: true

3. Apply the k8sgpt CR.

Expected behaviour

result objects should get created in the default namespace.

Actual behaviour

Getting below logs in the k8s-sample pod
