Forward port: #5040

Purpose

This pull request introduces a new "fail on deny" capability for consent nodes, allowing flows to be configured to fail if a user denies a consent prompt—even if all requested attributes and permissions are optional. The change includes backend logic, frontend UI updates, internationalization, and comprehensive tests.

Approach

Backend: Consent Denial Handling

  • Added the failOnDeny property (propertyKeyConsentFailOnDeny) to consent executor configuration, enabling strict flow failure when users deny consent or when the consent prompt times out.

Frontend: UI and Internationalization

  • Updated the consent properties panel (ConsentProperties.tsx) to include a checkbox for "Fail flow when user denies consent," with state management and change handling.
  • Added English translations and test mocks for the new property label and hint.

📝 Walkthrough

Walkthrough

Adds the failOnDeny consent node property across the backend, flow editor, translations, and documentation. Denied submissions and timeouts can fail the flow, while consent normalization fills omitted denied elements and preserves approved decisions.

Changes

Consent denial handling

Layer / File(s) Summary
Consent decision normalization
backend/internal/authn/consent/service.go, backend/internal/authn/consent/service_test.go
fillMissingDecisions fills omitted prompted elements as denied for denied root or purpose decisions. Approved decisions remain unchanged.
Strict consent execution
backend/internal/flow/executor/constants.go, backend/internal/flow/executor/consent_executor.go, backend/internal/flow/executor/consent_executor_test.go
The executor supports failOnDeny. Enabled flows fail after denied consent is recorded and fail timed-out prompts without recording consent.
Consent configuration surface
frontend/apps/console/src/features/flows/components/resource-property-panel/extended-properties/execution-properties/ConsentProperties.tsx, frontend/apps/console/src/features/flows/components/resource-property-panel/extended-properties/__tests__/ExecutionExtendedProperties.test.tsx, frontend/packages/i18n/src/locales/en-US.ts, docs/content/guides/consent.mdx, docs/versioned_docs/version-v1.0.x/guides/consent.mdx
The flow editor provides a failOnDeny checkbox. Translations, tests, and consent guides describe its behavior.

Estimated code review effort: 3 (Moderate) | ~25 minutes

Merge Risk: 🔵 Low · up to eadea

The PR adds configurable flow failure on consent denial, including timeout handling. It is mergeable with owner awareness that the associated denial test may be sensitive to prolonged CI pauses and could report a timeout rather than the intended denial result.

Warning

There were issues while running some tools. Please review the errors and either fix the tool's configuration or disable the tool if it's a critical failure.

🔧 ESLint

If the error stems from missing dependencies, add them to the package.json file. For unrecoverable errors (e.g., due to private dependencies), disable the tool in the CodeRabbit configuration.

docs/content/guides/consent.mdx

ESLint skipped: missing config or dependency (missing-dependency). The ESLint configuration references a package that is not available in the sandbox.
