Worked on stabilizing DNS endpoint configuration within the GoogleCloudPlatform/magic-modules repository, focusing on resolving an issue where the allow_external_traffic field could not be set alongside other dns_endpoint_config fields. Addressed this by appending allow_external_traffic to ForceSendFields, ensuring it is transmitted correctly with other configuration options. Updated both unit and integration tests to verify the new behavior and maintained alignment with Google Cloud API expectations by preserving protobuf marshalling semantics. Utilized Go, Terraform, and testing frameworks throughout the process. This work reduced deployment risk and support overhead by ensuring reliable DNS endpoint resource behavior across generated modules.
