Description

Sign-ups that continue into an enterprise SSO connection can fail with invalid_redirect_url ("Redirect url invalid") instead of redirecting to the identity provider, leaving the user with a flow that cannot be completed and reproduces on every retry.

What happens

completeSignUpFlow routes a sign-up that is still in missing_requirements. Its first branch hands off to the identity provider when enterprise_sso is a missing field:

if (signUp.missingFields.some(mf => mf === 'enterprise_sso')) {
  return signUp.authenticateWithRedirect({ strategy: 'enterprise_sso', redirectUrl, redirectUrlComplete, ... });
}

redirectUrl and redirectUrlComplete defaulted to '', so a caller that did not pass them sent:

{ "strategy": "enterprise_sso", "redirect_url": "", "action_complete_redirect_url": "" }

An empty string is not a valid redirect URL, so the request is rejected and the sign-up dead-ends. Because both values were optional with a silent default, omitting them was invisible at the call site — there was no type error and no local failure, only a rejected request at runtime.

Why so many steps could reach it

A sign-up usually does not know it requires enterprise_sso when the form is first submitted. The requirement appears once the identity behind the sign-up is resolved, which can be several steps later. Whichever step is active at that moment performs the hand-off — and most of them did not pass the redirect URLs:

Call site Passes redirectUrl Passes oidcPrompt
SignUpStart (×2) yes yes
handleCombinedFlowTransfer yes no
SignUpContinue no yes
SignUpEmailLinkCard no no
SignUpVerificationCodeForm no no
SignUpProtectCheck no no
EmailLinkVerify no no

Every combination of the two is represented, which points at parameters that are easy to forget rather than at one call site being wrong. All three values are derived identically from the sign-up context, which every one of these components already reads — so each call site was independently re-deriving values that are the same everywhere.

Only sign-ups that reached SSO directly from the first form were unaffected, which is why this did not show up on every SSO sign-up.

navigateToNextStepSignUp also omits the URLs, but it returns early unless missingFields is empty, so it cannot reach the branch. It is left as is.

The change

  • useCompleteSignUpFlow binds redirectUrl, redirectUrlComplete and oidcPrompt from the sign-up context once, along with navigate and the default handleComplete that six components were each repeating. Call sites now pass only the routing paths they genuinely differ on, so there is nothing left to forget.
  • EmailLinkVerify takes an explicit ssoCallbackUrl, supplied by the two sign-up render sites. It is shared with the sign-in flow, so it has no sign-up context of its own to bind — and its existing redirectUrl prop is not the SSO callback (SignInEmailLinkVerify passes ../factor-two), so that one cannot be reused.
  • completeSignUpFlow no longer defaults the two URLs to ''. If the SSO branch is reached without them it throws, so a future call site fails loudly and locally instead of producing a rejected request that surfaces to the user as a dead end. With the call sites bound this is unreachable from the UI; it exists to keep it that way.

SignUpContinue additionally passed a handleComplete that called removeClerkQueryParam for the ticket and invitation params — completeSignUpFlow already does exactly that in its complete branch immediately before invoking handleComplete, so the bound default is equivalent and those duplicated calls are dropped.

The branch ordering is unchanged: enterprise_sso is still evaluated before the protect-check routing, which is deliberate and already covered by prioritizes enterprise_sso over protect_check.

Bundle budget

The ui-common bundlewatch budget moves 132KB → 134KB, regenerated with pnpm bundlewatch:fix (its own formula — measured size plus 1KB, rounded up to the next KB). No other entry changed.

That chunk was already sitting within about 50 bytes of its ceiling. Building packages/ui at this branch and at origin/main puts the difference at 72 bytes gzipped, and CI reports the result 23 bytes over the 132KB limit. The added bytes are in common/EmailLinkVerify.tsx, which belongs to that chunk; the components simplified here are in the signup chunk, which is well under its own budget.

📝 Walkthrough

Walkthrough

Enterprise SSO sign-up continuation now validates redirectUrl and redirectUrlComplete before authentication. The useCompleteSignUpFlow hook centralizes completion, session activation, navigation, and redirect configuration across sign-up components. Email-link verification receives ssoCallbackUrl from sign-up context. Tests cover invalid redirect values and protect-check Enterprise SSO continuation.

Estimated code review effort: 4 (Complex) | ~45 minutes

Mergeability Score: 🔵 Low · up to 32465

The SSO sign-up redirect fix is otherwise mergeable, but EmailLinkVerify still needs the repository-required explicit TypeScript return type, warranting owner awareness or a follow-up.

Add coverage for the default completion handler.

The current tests assert only that setActive was called. Add a test with createdSessionId and a non-default afterSignUpUrl that invokes the setActive navigation callback and asserts the session and redirect URL passed to navigateOnSetActive.
