1. Linter failed to load package:

[Golang Lint (integration-tests/load)]

Source of Error:

level=warning msg="[runner] Can't run linter goanalysis_metalinter: inspect: failed to load package wasp: could not load export data: no export data for \"github.com/smartcontractkit/chainlink-testing-framework/wasp\""
level=error msg="Running error: can't run linter goanalysis_metalinter\ninspect: failed to load package wasp: could not load export data: no export data for \"github.com/smartcontractkit/chainlink-testing-framework/wasp\""

Why: The linter failed because it couldn't load the export data for the package github.com/smartcontractkit/chainlink-testing-framework/wasp.

Suggested fix: Ensure that the package github.com/smartcontractkit/chainlink-testing-framework/wasp is correctly installed and accessible. Verify the module path and dependencies.

3. Test failure due to unexpected service state:

	 	 	Listener is not connected

	 	+	service is "Unstarted", not started
	Test: 	TestHealthController_Health_body/text-failing

Why: The test TestHealthController_Health_body failed because the actual output included an additional service state (PromOTELForwarder being "Unstarted") that was not expected.

Suggested fix: Update the test expectations to include the state of the PromOTELForwarder service, or ensure that the PromOTELForwarder service is started before running the test.
