Status Code 503, Message=telemetry type is not supported

[StefanSa]

Hi @qclaogui
I get this error message when i try to send logs to the internal alloy.

ts=2024-11-04T14:11:02.880506132Z level=error msg="Exporting failed. Dropping data." component_path=/ component_id=otelcol.exporter.otlphttp.default error="interrupted due to shutdown: Throttle (0s), error: rpc error: code = Unavailable desc = error exporting items, request to http://172.17.34.36:34318/v1/logs responded with HTTP Status Code 503, Message=telemetry type is not supported, Details=[]" dropped_items=267

However, when i send metrics i have no problem with it.
Here is my alloy config

local.file_match "logs_integrations_integrations_node_exporter_direct_scrape" {
  path_targets = [{
    __address__ = "localhost",
    __path__    = "/var/log/{syslog,messages,*.log}",
    instance    = constants.hostname,
    job         = "integrations/node_exporter",
  }]
}

loki.source.file "logs_integrations_integrations_node_exporter_direct_scrape" {
  targets    = local.file_match.logs_integrations_integrations_node_exporter_direct_scrape.targets
  forward_to = [otelcol.receiver.loki.default.receiver]
}

otelcol.receiver.loki "default" {
  output {
      logs    = [otelcol.processor.batch.batch_loki.input]
  }
}


otelcol.processor.batch "batch_loki" {
  output {
    logs = [otelcol.exporter.otlphttp.default.input]
  }
}


otelcol.exporter.otlphttp "default" {
  client {
    endpoint = "http://172.17.34.36:34318"
  }
}

Internal alloy port config

- ALLOY_LOG_LEVEL=warn
    ports:
      - "12345:12345"
      - "34317:4317"
      - "34318:4318"

Do you have any idea what this could be?
