Problem
I can't send data to tempo or grafana agent via http sink. Here is sink config:
tempo_sink:
type: http
inputs:
- parse_message
compression: none
encoding:
codec: "json"
method: post
tls:
verify_certificate: false
verify_hostname: false
#uri: http://tempo.tempo.svc.cluster.local:4318/v1/traces
uri: http://grafana-agent.grafana.svc:4318
And here what I get:
2024-04-26T23:54:25.807049Z WARN sink{component_kind="sink" component_id=my-dev-sample-tempo_sink component_type=http}:request{request_id=1}:http: vector::internal_events::http_client: HTTP error. error=invalid HTTP version parsed error_type="request_failed" stage="processing" internal_log_rate_limit=true
If I forward tempo or grfana agent port 4318 to local machine I able to make POST request using curl, but Vector can't. If it is not a bug, please tell me where I missed something in config? The same instance of Vector is able to send logs to loki (sink loki) and elasticsearch. Tried with or without TLS and request sections. Vector is installed as Daemonset.

Can you try running with trace logs enabled and share those? Vector should output some information about each request it is making. I believe Vector will be making HTTP/1.1 requests. Maybe your endpoint only supports HTTP/2 or HTTP/3?
