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
