Description
Bug Report
Describe the bug
Certain OTLP log fields are dropped when output. Those fields are LogRecord.event_name, ResourceLogs.schema_url, ScopeLogs.schema_url. They're defined in the OTLP logs proto here.
To Reproduce
- Use this FB config
service:
flush: 0.2
pipeline:
inputs:
- name: opentelemetry
listen: 0.0.0.0
port: 4318
outputs:
- name: stdout
match: '*'- (Optional, can just use config above directly) Spin up a docker container:
docker run -ti -v <path/to/config/above>:/fluent-bit/etc/config.yaml:ro -p 4318:4318 -p 2020:2020 fluent/fluent-bit:3.2.10 -c /fluent-bit/etc/config.yaml
- Curl with log.json
curl -X POST http://localhost:4318/v1/logs -H "Content-Type: application/json" -d @log.json
Expected behavior
eventName and both schemaUrl references in JSON are present in output
Actual behavior
Data is missing in the output below:

{"schema"=>"otlp", "resource_id"=>0, "scope_id"=>0}
GROUP ATTRIBUTES :
{"resource"=>{"attributes"=>{"service.name"=>"fbtest"}}, "scope"=>{"name"=>"foo", "version"=>"1.0.0", "attributes"=>{"baz"=>42, "foo"=>"bar", "qux"=>["a", "b", "c"]}}}
