[pmcollins]

Describe your environment

OS: Mac
Python version: Python 3.9

What happened?

When you run the auto-instrumentation example published here without specifying a log exporter, two stacktraces are printed to the console at distro startup.

Steps to Reproduce

Run the example as specified before a workaround PR lands there (i.e. don't install otlp-proto-grpc or specify a log exporter).

Expected Result

Normal startup.

Actual Result

Two stacktraces are printed to the console

auto-instrumentation % opentelemetry-instrument --traces_exporter console --metrics_exporter none python server_automatic.py

Do you know if this this is a regression or it has been like that since a few?

[emdneto]

This error is expected no? I mean, you are not passing the --logs_exporter and the default is grpc. I don't think it's a regression @xrmx

We can probably handle this situation to not spam the error. I face it often when I forgot to install the grpc-exporter package
