OTLP metric to line protocol: failed to write point for gauge

[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

here is my Otel configuration

logs:

how i can resolve this error? could you please provide some info.

I also see the same issue, anyone find any solution to it?

Is this still the error? invalid tag value service.name="""

I am getting following error, still figuring out due to which I am getting this.
Actually I am using otel collector and there in logs I can see this error.

I also added comment to this issue open-telemetry/opentelemetry-collector-contrib#15242
