OTEL node Span attribute mappings

[alexanderlvov1]

Hello there. i have setup node-red to call my apigw and grafana tempo proxied by opentelemetry produces nice services graphs where my node-red and apigw are present. however node-red is always marked red, 100%, and so i started to wonder if i can use " Span attribute mappings" to fix these or there is some other way fix it as node-red part of the trace indicate error as shown here:
