Describe the bug
On trying to enrich the eBPF data with Kubernetes metadata, received an error fetching K8s Data

To reproduce
Steps to reproduce the behavior:

1. Deployed Vanilla sysflow with sf-processor.
2. Added clusterrole with name sysflow-agent
3. Added clusterrolebinding with name sysflow-agent
4. Edited daemonset.yaml, adding env in sfcollector container:
           - name: SF_K8S_API_URL
             value: https://kubernetes.default.svc/
           - name: SF_K8S_API_CERT
             value: /var/run/secrets/kubernetes.io/serviceaccount/token

Expected behavior
Should have enriched the Raw eBPF data with Kubernetes metadata (namespace, pod details etc)

Screenshots

Environment (please complete the following information):

• OS: Ubuntu 20.04.5 LTS
• SysFlow version: v0.5.0
• Container orchestration framework and version (if applicable): Civo K3s v1.22.11+k3s1
• Container runtime (if applicable): containerd://1.5.13-k3s1

Additional context
I verified that the node name represented by EXPORTER_ID in the sf-collector container is correct and present in my cluster.
