fix(mosaic): show the generic error when a verification send fails without details by alexcarpenter · Pull Request #10563 · clerk/javascript

alexcarpenter · 2026-10-31T02:35:04Z

Description

When sending a verification from the UserProfile add email or add phone dialog fails with a Clerk response that carries no errors (for example a 500 with data: []), save rejects with SaveError({}). The shared toFormError turned that into an empty error, so the dialog showed no message. It now returns the generic error, matching the fallback form.machine.ts already applies to the same rejection.

form.machine.ts keeps its own toFormError: it returns display strings, drops unknown fields and handles FormSubmitError, so it is not a duplicate of the shared one.

Walkthrough

toFormError now returns UNEXPECTED_ERROR as the global error when a SaveError contains neither a global nor field error. New tests cover this fallback and verify that email and phone add dialogs remain on the verify step and display the generic retry message when verification fails without error details.

Estimated code review effort: 2 (Simple) | ~10 minutes

Suggested reviewers: ephem, austincalvelage

Merge Risk: Moderate · up to fae2c

The fallback works, but the changed user-visible error flow lacks the required rendered feature coverage before merge.

Cover empty-send failures in the rendered feature tests.

The new email and phone cases exercise controller hooks and assert result.current.errorMessage. They do not verify the message rendered by the add-contact dialogs. The existing rendered add flows already cover adding an email and phone, while the existing generic-message assertions cover different reverification challenge failures.

Mosaic requires feature tests to own user-visible behavior. Move these empty-error cases to the existing email and phone feature tests, return an empty Clerk error response, and assert the visible generic message.
