Auto instrumentation is not working

Following the steps here https://opentelemetry.io/docs/instrumentation/python/automatic/example/#execute-the-automatically-instrumented-server

Run server first

opentelemetry-instrument --traces_exporter console --metrics_exporter none python server_automatic.py

Then run client

python client.py testing

}

Client do have output, but server automatic do not have any output, based on the doc here https://opentelemetry.io/docs/instrumentation/python/automatic/example/#execute-the-automatically-instrumented-server

The console running server_automatic.py will display the spans generated by instrumentation as JSON. The spans should appear similar to the following example:

Start with the automatic instrumentation example linked in the issue and reproduce the documented server and client commands using server_automatic.py and client.py. Compare the server console with the expected JSON spans in the documentation; done means the automatically instrumented server emits spans as described.
