What happened?

Description

Cannot access flags from span context. Making a statement that uses flags will fail.

Steps to Reproduce

Make & Use a transformer:

  transform:
    error_mode: ignore
    trace_statements:
    - context: span
      statements:
      - set(attributes["flags"], flags)

Expected Result

Spans will have a flags attribute that contain the flags values from the span context.

Actual Result

2024/08/19 17:23:35 collector server run finished with error: invalid configuration: processors::transform: unable to parse OTTL statement "set(attributes[\"collector_test_2\"], flags)": error while parsing arguments for call to "set": invalid argument at position 1: segment "flags" from path "flags" is not a valid path nor a valid OTTL keyword for the Span context - review https://github.com/open-telemetry/opentelemetry-collector-contrib/tree/main/pkg/ottl/contexts/ottlspan to see all valid paths
