HELM-480: Change handler return code by sowmya-sl · Pull Request #17042 · openshift/console

sowmya-sl · 2026-08-19T15:28:30Z

Analysis / Root cause:
Openshift console should return the correct HTTP return code
Test setup:
Openshift cluster
COOKIE="openshift-session-token-=MTc4NzE0MTMyMnxQ...Z4=; csrf-token=LoOs...;"

All error responses return proper HTTP status codes (400 Bad Request, 404 Not Found) instead of generic 502 Bad Gateway.

Walkthrough

Helm handlers now centralize error classification. Missing releases or revisions return 404, invalid request or chart data returns 400, and other failures return 502. Tests cover typed, wrapped, validation, and unknown errors.

Changes

Helm error classification

Layer / File(s)	Summary
Define Helm error status mapping `pkg/helm/handlers/handlers.go`	Adds centralized classification for missing resources, invalid inputs, and unknown failures.
Apply classification to Helm operations `pkg/helm/handlers/handlers.go`	Updates retrieval, upgrades, uninstall, rollback, release history, and asynchronous request parsing.
Update classification coverage `pkg/helm/handlers/handler_test.go`	Updates response and message expectations and adds coverage for 404, 400, and 502 mappings.

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

Merge Risk: 🟡 Moderate · up to 037db

Asynchronous Helm installs can still return 502 for invalid chart or revision errors instead of the intended 400 or 404 responses, so the API behavior remains inconsistent and should be corrected before merging.

path to expect HTTP 500 and the “Failed to get helm release” response body
produced by the handler’s final SendResponse branch, while preserving the
existing not-found expectations for matching “not found” or “no revision”
errors.
- Around line 216-220: Update all Helm handlers, including the release lookup
flow near the current string checks, to use the shared determineErrorStatusCode
classifier and errors.Is against the appropriate action or Helm driver
sentinels. Remove substring-based “not found”, “no revision”, and validation
classification, preserve explicit handling for validation errors such as “Chart
path is invalid”, and update affected tests for asynchronous install, rollback,
and release lookup status codes.

Replace per-handler ad-hoc error checks in 7 handlers with the classifier. Fix Cypress and RTL test assertions to match updated status codes and sentence-case microcopy.
