Description

This PR addresses the NotFoundError: Failed to execute 'removeChild' on 'Node': The node to be removed is not a child of this node. error.

Root Cause:
This error is not caused by application code but by a conflict between the Sentry Replay SDK (rrweb) and React's DOM reconciler. Specifically, rrweb patches Element.removeChild for session recording. During its initialization, rrweb attempts to patch adoptedStyleSheets, which fails with a TypeError on certain browser/OS combinations (e.g., Chrome 145 on Windows), likely due to a conflict with another browser mechanism or extension. This partial failure leaves rrweb's DOM tracking in an inconsistent state. When React's commitDeletionEffects later calls rrweb's patched removeChild during component unmounting, rrweb's internal state does not match the actual DOM, leading to the NotFoundError.

Solution Implemented:
To prevent this third-party error from cluttering Sentry, this PR adds the specific error message "Failed to execute 'removeChild' on 'Node'" to the ignoreErrors array in src/sentry.ts.

Why this approach:
This error is already caught by an ErrorBoundary and tagged as third-party code, indicating it's not directly fixable within our application logic. Ignoring it reduces noise in Sentry while the underlying issue in the Sentry Replay SDK (rrweb) is addressed. Future steps will involve upgrading the @sentry/react package to a version that contains fixes for the adoptedStyleSheets redefinition failure and exploring additional replay configuration options to prevent this scenario.

Code Example

// src/sentry.ts
Sentry.init({
  // ... other config
  ignoreErrors: [
    // ... existing errors
    "Failed to execute 'removeChild' on 'Node'",
  ],
});

Notable Changes

  • Added the specific error message "Failed to execute 'removeChild' on 'Node'" to the ignoreErrors array in src/sentry.ts.
  • This change prevents a known third-party NotFoundError from cluttering Sentry logs.
  • The underlying issue is a conflict between the Sentry Replay SDK (rrweb) and React's DOM reconciler, which will be addressed in future @sentry/react package upgrades.

Legal Boilerplate

Look, I get it. The entity doing business as "Codecov" is owned by Harness, Inc. In 2026 Harness acquired Codecov and as a result Harness is going to need some rights from me in order to utilize my contributions in this PR. So here's the deal: I retain all rights, title and interest in and to my contributions, and by keeping this boilerplate intact I confirm that Harness can use, modify, copy, and redistribute my contributions, under Harness's choice of terms.

Fixes GAZEBO-186Y
