Start with CentralDogmaPropertySupplierIntegrationTest, specifically testCDIntegration, and review the linked GitHub Actions run and its EndpointSelectionTimeoutException stack trace. Reproduce the failure and identify why the integration test cannot select its endpoint; done means the test runs reliably without this failure.
