fix(sdk): tolerate additive response fields by FrankSpitulski · Pull Request #5091 · NVIDIA/infra-controller

FrankSpitulski · 2026-08-18T04:23:09Z

Fix

The generated standard Go SDK rejected response fields not described by the OpenAPI schema. It now uses normal JSON decoding, which preserves required-field validation while tolerating additive response fields. This allows for existing Go SDK users to continue to use older versions when NICo is updated.

Validation

make generate-sdk
go test ./... from rest-api/sdk/standard

Summary by CodeRabbit

Bug Fixes
- JSON responses now accept additional, unrecognized fields without failing to decode.
Tests
- Added coverage for DPU machine response parsing, including network configuration, state, health information, and required-field validation.

Walkthrough

The generated Go model now permits unknown JSON fields. A new test validates DPU machine unmarshalling for representative metadata, network configuration, state, and health fields. The test also verifies failure when state is absent.

Changes

DPU machine JSON decoding

Layer / File(s)	Summary
Decoder behavior and validation `rest-api/openapi/templates/go/model_simple.mustache`, `rest-api/sdk/standard/dpu_machine_test.go`	`UnmarshalJSON` no longer enables `DisallowUnknownFields`. The test validates additive fields, nested values, key DPU machine fields, and the required `state` field.

Estimated code review effort: 2 (Simple) | ~10 minutes

Merge Risk: ⚪ Minimal · up to aee9c

The SDK now tolerates additive response fields while retaining required-field validation, improving compatibility with newer NICo responses; no actionable merge-blocking risk remains beyond normal checks and review.

- Around line 39-43: Add a subtest alongside the existing DpuMachine JSON
unmarshalling assertions that removes one schema-required field from the
response and verifies json.Unmarshal returns an error. Keep coverage for
additive fields accepted while preserving required-field validation.
- Around line 39-43: Extend the JSON unmarshalling assertions in the DpuMachine
test to validate representative decoded state and dpuNetworkConfig values from
the response payload, alongside the existing id, DMI, and health checks. Use the
corresponding DpuMachine fields and nested symbols already defined by the test
types.
