Affected Components

K8sGPT Version

v0.3.8

Kubernetes Version

v1.28.9-eks-036c24b

Host OS and its Version

No response

Steps to reproduce

helm repo add k8sgpt https://charts.k8sgpt.ai/
helm repo update
helm install release k8sgpt/k8sgpt-operator -n k8sgpt-operator-system --create-namespace
kubectl create secret generic k8sgpt-sample-secret --from-literal=openai-api-key=$OPENAI_TOKEN -n k8sgpt-operator-system
kubectl apply -f - << EOF
apiVersion: core.k8sgpt.ai/v1alpha1
kind: K8sGPT
metadata:
  name: k8sgpt-sample
  namespace: k8sgpt-operator-system
spec:

    model: gpt-3.5-turbo

kubectl apply -f - << EOF

kind: Pod
metadata:

          path: /
          port: 81
        initialDelaySeconds: 3
        periodSeconds: 3
EOF

Expected behaviour

❯ kubectl get results -o json | jq .
{
  "apiVersion": "v1",
  "items": [
    {
      "apiVersion": "core.k8sgpt.ai/v1alpha1",
      "kind": "Result",
      "spec": {
        "details": "The error message means that the service in Kubernetes doesn't have any associated endpoints, which should have been labeled with \"control-plane=controller-manager\". \n\nTo solve this issue, you need to add the \"control-plane=controller-manager\" label to the endpoint that matches the service. Once the endpoint is labeled correctly, Kubernetes can associate it with the service, and the error should be resolved.",

Actual behaviour

kubectl get results -o json | jq .
{
  "apiVersion": "v1",
  "items": [],
  "kind": "List",
  "metadata": {
    "resourceVersion": ""
  }
}

Additional Information

I execute the installation of the chart, create the secret with OPENAI_TOKEN declared and apply the K8sGPT CR, create a broken-pod as in the CLI example and when running the command to generate the CR results I receive a blank Json, when querying the results CR in the cluster through kubectl get results -A I receive an empty list. I configured the CLI with the same OPENAI_TOKEN and when I run k8sgpt analyze --explain I get the correct response, apparently no log or warn is displayed indicating any configuration problem with the operator pods, I would like to know what would be the next step to be able to perform the installation of the k8sgpt operato, I am available for any clarification!

can you check operator logs? there is a backOff in backend ai. make it enabled: false and test again
