Worked on enhancing data integrity and integration reliability for the Harness Go SDK and its Terraform provider by addressing a JSON serialization edge case in the MetricThresholdCriteriaSpec. Refactored the codebase to use pointers for float64 fields, ensuring accurate handling of zero, non-zero, and nil values, and expanded test coverage to validate these scenarios. Updated the harness/terraform-provider-harness repository to depend on the latest harness-go-sdk release, aligning both projects for improved compatibility and release readiness. Leveraged Go programming, backend development, and dependency management skills to reduce runtime errors and improve the stability of metric threshold configurations across the codebase.
