Problem Statement
As mentioned in https://opentelemetry.io/docs/languages/python/automatic/configuration/, there is a mention of OTEL_PYTHON_LOG_CORRELATION which when set to true, will automatically inject trace id and span id in context to python's logs:

export OTEL_PYTHON_LOG_CORRELATION=true export OTEL_PYTHON_LOG_FORMAT="%(msg)s [span_id=%(span_id)s]" export OTEL_PYTHON_LOG_LEVEL=debug export OTEL_PYTHON_LOGGING_AUTO_INSTRUMENTATION_ENABLED=true 

However, setting the environment does NOT inject the trace_id and span_id, and the generated span has 0x0 as their values. In fact, when I tried to find the OTEL_PYTHON_LOG_CORRELATION in Otel python repo in github, I couldn't find any mention of it in the codebase.

Steps to reproduce
Describe exactly how to reproduce the error. Include a code sample if applicable.

1. Write a simple python app (e.g. flask application), and use python's logging and generate a log.
2. define the following env:

... - OTEL_EXPORTER_OTLP_PROTOCOL=http/protobuf - OTEL_LOGS_EXPORTER=console,otlp_proto_http - OTEL_PYTHON_LOG_CORRELATION=true - OTEL_PYTHON_LOGGING_AUTO_INSTRUMENTATION_ENABLED=true ... 

3. run the application, with

What is the expected behavior?
OTEL log payload should have trace_id and span_id correctly populated

What is the actual behavior?
The console output has 0x00.. values for trace_id and span_id.
