Description
Describe your environment
OS: Linux/amd64
Python version: Python 3.12
SDK version: I installed following libs using pip, so I assume the latest version (opentelemetry-exporter-otlp opentelemetry-instrumentation-requests opentelemetry-instrumentation-flask)
API version: I installed following libs using pip, so I assume the latest version (opentelemetry-exporter-otlp opentelemetry-instrumentation-requests opentelemetry-instrumentation-flask)
What happened?
It seems that I can't disable context propagation in Python by setting the OTEL_PROPAGATORS ENV variable to none as mentioned here.
When trying to do so, I get the following error:
{
"message": "Uncaught exception",
"traceback": "Traceback (most recent call last):

During handling of the above exception, another exception occurred:

ValueError: Propagator none not found. It is either misspelled or not installed."
}
It seems that error happens at this line and it's because we are missing the none propagator definition here in opentelemetry-api/pyproject.toml. (I am not a python expert, so my assumption can be wrong)
Steps to Reproduce
- set
OTEL_PROPAGATORS=none - run the app
Expected Result
No errors are expected, and automatic propagation is disabled.
Actual Result
Error that the none propagator is not defined.
Additional context
I am not sure if setting the OTEL_PROPAGATORS="" will be valid, but according to the documentation, none should be a valid value.
Would you like to implement a fix?
None
