Two Integration Test check failures exist and are expected due to test coverage failures, they are unrelated to this PR.

[crobert-1]

Tests are failing because of open-telemetry/opentelemetry-collector#12981, tests need to be updated to properly account for upstream change.

[crobert-1]

It's no longer valid to pass an empty config and expect a non-nil response from confmap. The test case should be updated to contain valid "default" information for the component that is not empty. 👍

[jvoravong]

The two failing check for the integration tests will be fixed in a separate PR.
