SigNoz Otel Collector Shows "Empty Batch, Skipping" – No Metrics Exported

[johndariel]

I'm using self-hosted SigNoz, and my otel-collector keeps logging empty batch, skipping from the ClickHouse metrics exporter—no metrics are being sent; how can I fix this?

LOGS
{"level":"warn","ts":"2025-07-08T08:00:25.493Z","caller":"clickhousemetricsexporter/exporter.go:395","msg":"empty batch, skipping","resource":{"service.instance.id":"cd0b142b-b371-4d96-af15-fe2170ddb810","service.name":"/signoz-otel-collector","service.version":"dev"},"otelcol.component.id":"clickhousemetricswrite","otelcol.component.kind":"exporter","otelcol.signal":"metrics"}

Thanks in advance
