OTLP trace forwarding to Grafana Tempo fails (415 Unsupported Media Type)

[Akartosh]

Question

I'm trying to receive otlp traces from my services with vector and sending them to grafana/tempo as storage backend
Codec which i tried said there source trace and sinks logs format except "native" codec. But now grafana tempo is not supported this media type
As i know tempo can receive otlp traces from services straight but i can't do this with vector

Vector Config

sources:
  otel_traces:
    type: "opentelemetry"

sinks:
  tempo:
    type: opentelemetry
    inputs:
      - otel_traces.traces
    protocol:
