#8880

Summary by CodeRabbit

  • Bug Fixes
    • Site-loading failures now display a clear error state instead of a loading skeleton.
    • Error messages are surfaced more consistently for store and site requests, including incomplete or string-based error details.
    • Site data initializes safely when initial state information is unavailable.
    • Users are redirected to the Studio when active-site validation fails outside the Studio area.
    • Site-loading errors are cleared when a new request starts or completes successfully.

Walkthrough

The PR adds typed, normalized site-loading errors to global state. Site initialization and fetch epics dispatch failures with extracted payloads. Site management renders an error state, and active-site lookup failures redirect non-/studio paths.

Changes

Site error flow

Layer / File(s) Summary
Sites error state contract
studio-ui/ui/app/src/models/GlobalState.ts, studio-ui/ui/app/src/state/actions/sites.ts, studio-ui/ui/app/src/state/reducers/sites.ts
The sites state now stores an ApiResponse error. Failure actions carry the error payload. Reducers initialize, clear, and record the error.
Site fetch error dispatch
studio-ui/ui/app/src/state/epics/sites.ts, studio-ui/ui/app/src/state/store.ts, studio-ui/ui/app/src/utils/ajax.ts
AJAX errors are normalized before failure actions are dispatched. State initialization handles failed site requests and redirects non-/studio paths after active-site lookup failures.
Site error rendering
studio-ui/ui/app/src/components/SiteManagement/SiteManagement.tsx, studio-ui/ui/app/src/components/CrafterCMSNextBridge/CrafterCMSNextBridge.tsx
SiteManagement renders ErrorState when site loading fails. The bridge stores string errors or messages from error objects.

45-48: 🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win

Clear a previous error when a new site fetch starts.

When fetchSites runs after fetchSitesFailed, this branch sets isFetching to true but preserves the old error. SiteManagement.tsx checks error before isFetching at Line 231, so a retry continues to display the old ErrorState instead of the loading skeleton until the request completes.

Clear the error when the fetch starts.

Proposed fix
 .addCase(fetchSites, (state, action) => ({
 	...state,
-	isFetching: true
+	isFetching: true,
+	error: null
 }))

@jvega190 I recommend that you do not merge this PR yet.

One blocking issue remains in studio-ui/ui/app/src/utils/ajax.ts.

extractErrorPayload declares an ApiResponse return type. It can return a string when the API returns a plain-text response body. This can occur in both paths added by this PR:

  • Initial store loading in studio-ui/ui/app/src/state/store.ts.
  • Site reloads in studio-ui/ui/app/src/state/epics/sites.ts.

catchAjaxError can also pass a string response to extractErrorPayload. The type contract is therefore not valid at runtime. This can lose the server error message in ApiResponseErrorState consumers.

Normalize a selected string response into an object before returning it:

export const extractErrorPayload = (error: AjaxError): ApiResponse => {
	const response = error?.response?.response ?? error?.response;
	return typeof response === 'string'
		? { code: error?.status, message: response }
		: response ?? {
				code: error?.status,
				message: 'An unknown error has occurred.'
			};
};

The previous retry issue is fixed. fetchSites now clears error before it sets isFetching.

I also found no focused tests for extractErrorPayload, fetchSitesFailed, fetchStateInitialization, or SiteManagement. Add coverage for plain-text, object, and missing error responses. Travis CI is still queued, and the PR remains a draft.

@jvega190 The previous blocking issue is fixed. extractErrorPayload now normalizes plain-text responses to an ApiResponse, so the sites failure paths have a consistent error contract.

I found no additional blocking source issue in the current changes.

The PR is not ready to merge yet because GitHub reports these merge gates:

  • The PR is still a draft.
  • Travis CI is still queued.
  • GitHub requires a review.
  • The merge state is BLOCKED until those conditions are satisfied.

I recommend focused tests before merge. Cover these cases:

  • extractErrorPayload with a plain-text response, an object response, and no response.
  • fetchSitesFailed state updates.
  • Initial store loading when fetchAll() fails.
  • SiteManagement rendering when sites.error is set.

After Travis CI passes, the PR leaves draft status, and the required review is present, I see no remaining code-level blocker.
