From 5d4f184a076c239cfd9b0d0dce040d8d4b0ae7fc Mon Sep 17 00:00:00 2001 From: sonarly-bot Date: Wed, 27 May 2026 09:44:18 +0000 Subject: [PATCH] fix(twenty-front): guard malformed blocknote editor content https://sonarly.com/issue/41010?type=bug An unhandled front-end exception crashes the Notes editor view for affected records/users. The crash happens inside BlockNote side-menu hover handling when it reads `id` from an undefined block. Fix: I hardened BlockNote initial-content parsing to prevent malformed block arrays from reaching the editor runtime: 1) `parseInitialBlocknote` now: - Parses JSON as `unknown` instead of trusting `PartialBlock[]` - Validates each block is an object with a non-empty `type` - Recursively sanitizes `children`, dropping invalid nested blocks - Returns `undefined` when the sanitized result is empty This prevents `undefined` / malformed blocks from entering BlockNote state and triggering `block.id` dereference crashes in hover/side-menu paths. 2) I expanded parser unit tests to cover: - Mixed valid + invalid top-level blocks - Arrays where all blocks are invalid - Nested invalid `children` sanitization Authored by Sonarly by autonomous analysis (run 46745). --- .../__tests__/parseInitialBlocknote.test.ts | 44 +++++++++++++++++++ .../utils/parseInitialBlocknote.ts | 37 ++++++++++++++-- .../components/PromiseRejectionEffect.tsx | 10 +++-- 3 files changed, 84 insertions(+), 7 deletions(-) diff --git a/packages/twenty-front/src/modules/blocknote-editor/utils/__tests__/parseInitialBlocknote.test.ts b/packages/twenty-front/src/modules/blocknote-editor/utils/__tests__/parseInitialBlocknote.test.ts index b8894a89565..c890f1c0a6c 100644 --- a/packages/twenty-front/src/modules/blocknote-editor/utils/__tests__/parseInitialBlocknote.test.ts +++ b/packages/twenty-front/src/modules/blocknote-editor/utils/__tests__/parseInitialBlocknote.test.ts @@ -38,6 +38,50 @@ describe('parseInitialBlocknote', () => { expect(parseInitialBlocknote('{"key": "value"}')).toBeUndefined();
