Unable to run OTEL as Collector mode and gateway mode

[ramesh569]

Hi , i am trying to setup logging mechanisam on aks cluster using OTEL agent. we would like to have approach like
Agent as sidecar - cluster collector receiver - gateway mode to splunk observability.

tried to deploy only custer receiver which exports to gateway then splunk observability.
as part of cluster receiver configuration, removed signalfx exporter by setting as null so that it can forwards logs/metrics/traces to gateway instead of splunk observability directly. however i see collector is trying to send directly to splunk not to gateway.

this values.yaml file

values_receiver.yaml

below is the error log
