I solved the issue, for reference, the issue was that otel-agent was not spawned properly, in my case because it was missing permissions

Error creating: pods "signoz-k8s-infra-otel-agent-9zwsc" is forbidden: violates PodSecurity "baseline:latest": hostPath volumes (volumes "varlog", "varlibdockercontainers", "hostfs"), hostPort (container "signoz-k8s-infra-otel-agent" uses hostPorts 13133, 4317, 4318, 8888)
