Thanks for opening this @salasberryfin. I forgot to mention - rancher/cluster-api-addon-provider-fleet#240 need to be included into addon config in order for HelmApp feature to be enabled. Would you be ok to add it or shall I push to the branch?

Basically it needs

    featureGates:
      configMap:               # ConfigMap state configuration settings (optional)
        ref:               
          kind: ConfigMap
          apiVersion: v1
          name: rancher-config
          namespace: cattle-system
      experimentalOciStorage: true   # Enables experimental OCI storage support
      experimentalHelmOps: true

Seems to be an issue with expectations on fleet key in configMap, it should be optional:

status:
  conditions:
  - lastTransitionTime: "2025-04-24T09:17:01Z"
    message: 'FleetAddonConfig reconcile error: Fleet chart patch error: FleetSettings
      read error: Error deserializing response: missing field `fleet` at line 1 column
      972'

I’ll prepare a fix for this.
