Custom Logs doesn't works with ECK

Hi,
i have tried to install this solution cloud-on-k8s/config/recipes/elastic-agent/fleet-custom-logs-integration.yaml at main · elastic/cloud-on-k8s · GitHub but the package custom logs is not present in the elk policy. When the kibana start i have seen this error

The version that i use of components are

kibana,elastic,fleet,elastic-agent : 8.13.2
eck operator: 2.12
log: 2.3.1

The configuration works until log 1.1.2 from 2.0.0 doen't works
