[UI] Keep non-serializable values out of Notification Center state - #23082
The events slice stored the notification ui payload exactly as it arrived, icon component included, which is what set off the Redux warning about a non-serializable value in the events state.
This screens the payload in openNotificationCenter before it reaches state. Only serializable values are kept, a Date, Map, Set, class instance or circular object gets dropped. The icon is stored as a name now, and the NotificationCenter resolves it to the component when rendering.
New tests cover the screening, including Date, Map, Set, class instance and circular cases, and the icon resolution. ESLint is clean on the changed files.
Summary by CodeRabbit
New Features
Notification centers support bell, alert, error, and info icons, with the bell icon used by default.
Bug Fixes
Unknown, unsupported, or missing icon settings now display the bell icon instead of an invalid icon.
Invalid notification-center display settings are ignored, while valid settings and defaults are retained.
Non-serializable UI values are filtered out, and invalid view selections fall back to the initial view without disrupting valid selections.
No actionable comments were generated in the recent review.
Walkthrough
The events slice now filters Notification Center UI values for serializability. The Notification Center resolves configured icon names to registered icon components and uses the bell icon for unsupported inputs.
Changes: Notification Center configuration
Layer / File(s)
Summary
Filter notification UI state ui/store/slices/events.ts, ui/store/slices/__tests__/events.test.ts
The events slice filters supplied UI values for serializability before merging them into state. Tests cover supported and unsupported values, action payloads, and reset behavior.
The Notification Center resolves registered icon names to components and uses the bell icon for non-string or unknown values. Tests cover registered names and fallback cases.
Notification Center state now screens out non-serializable values, and icon names are resolved to components with a bell fallback. The earlier concern about arrays with named properties is addressed. No merge-blocking issues remain.

Explanation
The title says the change keeps non-serializable values out of Notification Center state. The changeset matches this. In events.ts, isSerializable filters view_to_open and incoming UI properties in openNotificationCenter before they merge into state. The icon is stored by name and resolved to a component in NotificationCenter via resolveNotificationIcon. The title names the main change and stays specific to the Notification Center.
Full details: Linked Issues check
Explanation
Issue #16873 requires serializable Notification Center state. The events.ui.icon value must be a string identifier or be removed. The identifier-to-component mapping must occur in the UI during rendering.
At the reviewed head:
ui/store/slices/events.ts adds isSerializable, and the summary states that it rejects functions, symbols, bigints, non-plain instances (Date, Map, Set, class instances) and cycles. openNotificationCenter filters payload.ui through this guard. It also checks view_to_open and falls back to the initial view when the value is invalid.
ui/components/layout/NotificationCenter/notificationIcons.ts maps the names bell, alert, error, and info to icon components. I read the file at head. resolveNotificationIcon uses Object.hasOwn, so prototype-chain names such as constructor and __proto__ return the bell default.
ui/components/layout/NotificationCenter/index.tsx calls resolveNotificationIcon(uiConfig.icon) during rendering.
Tests cover payload screening, view_to_open handling, and icon resolution, including the prototype-chain cases.
The reviewed code meets the coding requirements of #16873. Non-coding items are not assessed. The change since the previous review is small (events.ts now +36/-5). The current summary is consistent with the earlier conclusions, and the icon resolver source confirms the lookup behavior.

Explanation
Each changed file serves the #16873 objective:
ui/store/slices/events.ts: adds the serializability guard, applies it to payload.ui and view_to_open in openNotificationCenter, and exports the action creator for testing.
ui/components/layout/NotificationCenter/notificationIcons.ts: adds the name-to-icon map, the default name, and resolveNotificationIcon.
ui/components/layout/NotificationCenter/index.tsx: resolves the header icon at render time (+2/-1).
ui/store/slices/__tests__/events.test.ts and notificationIcons.test.ts: test the new behavior.
The event revision, paging, and retry code in events.ts is existing implementation. It is not a change introduced by this pull request. No unrelated functional change was identified.

This is a clean fix for #16873: screening the payload at the slice boundary is the right place, the icon-as-name approach keeps the store serializable, and the tests cover the tricky cases (circular refs, shared refs, class instances) well. One real hole: resolveNotificationIcon indexes the map directly, so a prototype-chain name like 'constructor' or '__proto__' returns a non-component instead of falling back to the bell, and the header would then try to render it. Also note view_to_open in the same reducer is still assigned to state unscreened, so a non-serializable value there would bring the warning back.

Direct indexing falls through to the prototype chain: resolveNotificationIcon('constructor') returns Object and '__proto__' returns Object.prototype, so the header would try to render a non-component instead of falling back to the bell. Guard with an own-property check:
Fixed the icon lookup, it now uses Object.hasOwn so names like constructor or proto fall back to the bell. Added tests for those names.
For view_to_open, you are right, it was going into state unscreened in the same reducer. It is checked with the same isSerializable guard now, with a test added.

Check named array properties before accepting an array.
If a UI value is const items = []; items.extra = new Date(), isSerializable(items) returns true. The array iteration checks indexed elements but skips extra. openNotificationCenter then retains that Date in state.ui. Check the array’s own values, including named properties, before accepting it.

Good work! You might like to present your work in the upcoming, weekly Meshery development meeting (meshery.io/calendar). If so, I encourage you to add this item in the meeting agenda (meet.meshery.io/dev-minutes), attend, present, and receive feedback.

Iterating an array only visits its indexed elements, so a named property
carrying a function (e.g. list.onSelect) passed the serializability screen
and could still land in Notification Center state. Read array entries
through its keys so named properties are screened too, and cover both
cases with tests.

Reviewed the change against #16873 and Pontus's review.
Screening at the slice boundary is the right fix: openNotificationCenter now drops non-serializable ui values and view_to_open, and the icon travels as a name resolved at render time.
Pontus's prototype-chain point is addressed: resolveNotificationIcon uses Object.hasOwn, with tests covering constructor, proto and toString, and view_to_open is screened with the same isSerializable guard.
One remaining hole I fixed directly: isSerializable iterated arrays by index only, so an array carrying a named property holding a function (list.onSelect) passed the screen. It now reads array entries through Object.keys, with tests for both the rejection and the serializable-named-property case (92d1b3c).
Local verification: targeted vitest run on events.test.ts and notificationIcons.test.ts, 44 passed; ESLint clean on all five changed files.
Also worth taking up @alexquincy's suggestion to present this at the weekly Meshery development meeting.
Approving; merging once CI is green on the updated head.
