feat(ui,shared,localizations): dedicated screen for a blocked request#9600zourzouvillys wants to merge 7 commits into
Conversation
A blocked sign-in or sign-up is terminal — there is no field to correct and no retry that helps — but it currently renders in the same small inline error slot as "incorrect password", with nothing the user can act on or quote. It now replaces the card. The screen shows a short reference for the request so the end user can quote it to support, and renders the application's own title, description and https link when it supplies them. - shared: `trace_id`, `title`, `description`, `link_url` and `link_text` on the API error meta, parsed to camelCase alongside the existing fields. - ui: ActionBlockedCard plus a `useActionBlocked` hook. The hook wraps `card.setError`, which is where every error in these flows already funnels, so both the submit path and the OAuth-callback path are covered without either knowing about it. - ui: new appearance descriptors and an `actionBlocked` flow part. - localizations: `actionBlocked.title`, `.subtitle` and `.traceIdLabel` as the fallbacks used when the application supplies no wording of its own. Additive and degrades safely: the error's code, message and long_message are unchanged, so an older client is unaffected, and a response carrying no meta renders exactly the inline error it did before. The application-supplied text is rendered as text nodes, never as markup, and only `https` links become an href — the URL is validated before it is sent, and checked again here before it reaches the DOM. Verified: `pnpm --filter @clerk/ui type-check` reports no errors in any changed file, and `@clerk/shared` and `@clerk/localizations` build clean. 17 new tests pass, covering the meta parsing and every rejected URL scheme. The 24 failing test files and the type errors that remain are all under `src/mosaic/**`, which this change does not touch — they fail on an unbuilt `@clerk/headless`.
errorToJSON has its own exhaustive meta field list and backs Verification.__internal_toSnapshot, so on the SSR/hydration path a verification error lost the reference and the application's message. The blocked screen then degraded to its generic wording with nothing saying why — and that is the OAuth and SAML path, one of the two the screen is wired for. Both directions of the meta mapping are hand-maintained lists, so a field added to one and not the other is dropped silently. Added a round-trip test that fails if either side stops carrying them; verified it fails when the mapping is removed, so it is a real check and not a passing no-op.

CI's "Verify localizations are generated" step failed: adding a key to en-US requires regenerating all 48 locale files, which was not obvious from the local build (both @clerk/localizations and @clerk/shared build clean without it). Untranslated locales get `undefined` and fall back to en-US at runtime, which is the existing pattern for a newly added key.
…creen codex review found the gap: when a challenge is submitted and the request is then blocked, useProtectCheckRunner routes the error through handleError(..., card.setError). The interception lived only in the two start components, so that card rendered an inline error with a RETRY button — for something that cannot succeed. Moved detection into the shared card state, where every error in these flows already funnels. It happens before translateError, which flattens the error to a string and discards the meta the screen is built from. Consequences: - The four cards that can show the screen now read `card.blockedDetails`; the per-component hook is gone, and a card that wants the screen is one guard. - The pure helpers moved to utils/actionBlocked.ts so card state can use them without importing the card and creating a cycle. New tests cover the central predicate specifically, because a false positive there would replace a correctable form error with a dead end: it fires only on action_blocked, only with details, and ignores strings, numbers, null and undefined. 21 tests pass; type-check clean across every file this touches.

Route restored blocked errors through blocked-request detection.
CardStateProvider passes window.Clerk.__internal_last_error directly to translateError during initialization and route changes. For a fraud_action_blocked error with metadata, state.blockedDetails remains unset and the translated value is stored as state.error, so the flow can skip ActionBlockedCard and show retry UI. Apply actionBlockedDetailsFrom before translation and clear error when details exist.

Two additions the API can now send, both for an application that wants to render its own screen rather than the built-in one: - `kind` — a tag naming why the request was blocked, e.g. `vpn_detected`. - `data` — arbitrary scalars the application's owner attached. Neither is RENDERED. They are read off the meta, carried through the snapshot round trip, and exposed on the error for an application to switch on. Rendering `data` would put somebody's internal keys in front of an end user, which is the opposite of what it is for. A blocked request carrying only a kind, or only data, now counts as something to show — that is precisely the integration this serves, and treating it as empty would have fallen back to the inline error for exactly those applications. Both directions of the meta mapping are hand-maintained lists, so both were updated together and the round-trip spec covers the new fields. Verified: 24 ui predicate tests and 3 shared round-trip tests pass; type-check clean on every file this touches; @clerk/shared and @clerk/localizations build.
…onfigured The changeset claimed they were unchanged. That was true when the wording lived only on `meta`; it stopped being true once the owner's title and description started driving them, which is what makes a client that renders only those show the configured wording rather than the generic sentence.

blockedDetails was set and never cleared, so once a card had shown the blocked
screen it could not show anything else.
That is worse than it sounds, because clearing an error is how these flows
START one: handleClerkApiError calls setGlobalError(undefined) before setting
the real error, and the protect-check runner calls card.setError(''). Both
cleared `error` and left `blockedDetails` in place — so after any block, the
next genuine error on that card would have been invisible behind a terminal
screen the user could not leave.
setError now owns both fields, which is the invariant that was missing: a
blocked error sets the screen, and anything else clears it.
Found while investigating the CI failures. It is NOT their cause — those are
`Too many requests` from the shared test backend, which is also failing
unrelated branches — but it is a real defect and nothing would have caught it.
The new tests would: verified they fail when the clear is removed.

Summary
When a sign-in or sign-up request is blocked, the user currently sees one generic sentence in the same small inline error slot that carries "incorrect password" — with nothing to act on and nothing to quote if they contact support.
A blocked request is terminal: there is no field to correct and no retry that helps. This gives it its own screen instead of an inline error, shows a short reference the user can quote, and renders the application's own wording when the API supplies it.
What the user sees
Everything above the reference comes from the application's configuration and is optional. The reference is shown whenever the API sends one.
The contract
The API may include these on an
action_blockederror'smeta:trace_idtitledescriptionlink_urlhttpsURL for help.link_textkindvpn_detected.dataAll optional. They are parsed to camelCase alongside the existing meta fields.
kindanddataare carried, never displayed. They exist so an application can render its own UI instead of this screen:Rendering
datawould put an application's internal keys in front of an end user, which is the opposite of what it is for.Backwards compatibility
Additive, and this is the part worth checking in review:
codeis unchanged, so an older client keeps working.One deliberate change:
messageandlong_messagenow carry the application owner's own wording when they configured any (and the reference appended). That is so a client rendering only those — rather than this screen — shows what the owner wrote instead of the generic sentence. With nothing configured they are unchanged.Implementation
@clerk/shared— the fields onClerkAPIErrorJSONandClerkAPIError, parsed inclerkApiError.ts.@clerk/ui—ActionBlockedCard, plus detection in the shared card state. That is where every error in these flows already funnels, so the form-submit path, the OAuth-callback path and a challenge submission that is then denied are all covered without any of them knowing about it.@clerk/ui— new appearance descriptors (actionBlockedIconBox,actionBlockedIcon,actionBlockedLink,actionBlockedTraceIdBox,actionBlockedTraceIdLabel,actionBlockedTraceId) and anactionBlockedflow part, so the screen is customizable like any other.@clerk/localizations—actionBlocked.title,.subtitleand.traceIdLabelas the fallbacks used when the application supplies no wording.Two fixes folded in, both found by review rather than by the suite:
errorToJSONdropped these fields. It has its own exhaustive meta list and backsVerification.__internal_toSnapshot, so on the SSR/hydration path a verification error lost them and the screen degraded to generic wording with nothing saying why — on the OAuth and SAML route specifically, one of the two this screen is wired for. Both directions of that mapping are hand-maintained lists, so a round-trip test now fails if either side stops carrying them.useProtectCheckRunnerroutes that error throughhandleError(..., card.setError), and interception used to live only in the two start components — so that card showed an inline error with a Retry button, for something that cannot succeed. Moving detection into card state fixed it for every card at once.Security
The title, description and link are written by the application's owner and rendered in an end user's browser, so:
httpslinks become anhref. The URL is validated before it is sent, and checked again here before it reaches the DOM — the second check is what stands between a value that arrived anyway and ajavascript:ordata:URI. A link that fails is dropped and the rest of the card still renders.rel="noopener noreferrer", since the destination is not necessarily under the owner's control once followed.Verification

(The type errors and failing test files that remain are all undersrc/mosaic/**, which this PR does not touch — they fail on an unbuilt@clerk/headless.)pnpm --filter @clerk/shared buildandpnpm --filter @clerk/localizations build— clean.

I verified this test actually fails when the mapping is removed rather than trusting a green run.Note on CI: the integration suite is currently failing repo-wide, on branches unrelated to this one — including a dependency-bump branch with no UI code. Those failures are not from this change.
A changeset is included.
