[jagratac]

I am tring to get metrics form Pixie telemetry -> Otelp(otel agent ) -> Otel-gateway -> influxDB os: Ubuntu 22.04 version: influx container 2.3.0-alpine "2023-08-23T04:03:57.940Z error exporterhelper/queued_retry.go:401 Exporting failed. The error is not retryable. Dropping data. {"kind": "exporter", "data_type": "metrics", "name": "influxdb", "error": "Permanent error: failed to convert OTLP metric to line protocol: failed to write point for gauge: Permanent error: failed to encode point: encoding point 22: invalid tag value service.name=""", "dropped_items": 2570} go.opentelemetry.io/collector/exporter/exporterhelper.(*retrySender).send go.opentelemetry.io/[email protected]/exporter/exporterhelper/queued_retry.go:401 go.opentelemetry.io/collector/exporter/exporterhelper.(*metricsSenderWithObservability).send go.opentelemetry.io/[email protected]/exporter/exporterhelper/metrics.go:136 go.opentelemetry.io/collector/exporter/exporterhelper.(*queuedRetrySender).start.func1 go.opentelemetry.io/[email protected]/exporter/exporterhelper/queued_retry.go:205 go.opentelemetry.io/collector/exporter/exporterhelper/internal.(*boundedMemoryQueue).StartConsumers.func1 go.opentelemetry.io/[email protected]/exporter/exporterhelper/internal/bounded_memory_queue.go:61"
