From 77c9079d4c4ef9cff31891f30d2c7c5a58a85a67 Mon Sep 17 00:00:00 2001 From: khaylebfortune <111098422+khaylebfortune@users.noreply.github.com> Date: Thu, 22 Oct 2026 14:36:29 +0000 Subject: [PATCH 1/2] fix(frontend): surface errors and keep dialog open on useConfirmedMutation action failure handleConfirm previously used a finally block with no catch, so when the wrapped action rejected the confirmation dialog still closed as if the operation succeeded, no error was surfaced to the caller or user, and the rejection became an unhandled promise rejection (since handleConfirm is invoked as an event handler rather than awaited by its caller). Now on action rejection the dialog stays open, loading is cleared, and an error toast is surfaced via useToastStore. This mirrors the behavior of useTransactionPreview.confirm(). Adds a test covering the rejecting-action case, asserting the error is surfaced rather than the dialog silently closing.
