• The ImportError handler comment still refers to “events” (e.g., “If the events is not available…”) even though the events setup block was removed. Please update the comment to refer to logging (and adjust the wording so it matches the actual failure being caught).

    except ImportError as ex:
        # If the events is not available, we will not set it up.
        # This could possibly be due to breaking change in upstream OpenTelemetry
        # Advise user to upgrade to latest OpenTelemetry version
        _logger.warning(  # pylint: disable=do-not-log-exceptions-if-not-debug
            "Exception occurred when setting up Logging. Please upgrade to the latest OpenTelemetry version: %s.",
