The default helm chart currently is causing these errors between the loadbalancer component and the sampler component:

ts=2024-11-26T08:11:20.173058507Z level=error msg="Exporting failed. Dropping data." component_path=/ component_id=otelcol.exporter.loadbalancing.default error="not retryable error: Permanent error: rpc error: code = ResourceExhausted desc = grpc: received message after decompression larger than max (4449633 vs. 4194304)" dropped_items=2550

This is caused due to gRPC message size exceeding the 4mb default: https://pkg.go.dev/google.golang.org/grpc#MaxRecvMsgSize
