Filter non-actionable "removeChild" DOM errors from Sentry (#8451) (#8462)

iHiD · claude · web-flow · commit f0b3e9841a54 · 2026-02-09T10:48:39.000Z
The "NotFoundError: Failed to execute 'removeChild' on 'Node'" is thrown by third-party scripts (reCAPTCHA, blob-loaded widgets) when they try to clean up DOM nodes that React has already unmounted. These errors are not actionable and create noise in Sentry. Closes #8451 Closes #8455 Co-authored-by: Claude Opus 4.6 <noreply@anthropic.com>
