Ubbe 301d7cbada fix(frontend): suppress cross-origin stylesheet security error (#12086)
## Summary
- Adds `ignoreErrors` to the Sentry client configuration
(`instrumentation-client.ts`) to filter out `SecurityError:
CSSStyleSheet.cssRules getter: Not allowed to access cross-origin
stylesheet` errors
- These errors are caused by Sentry Replay (rrweb) attempting to
serialize DOM snapshots that include cross-origin stylesheets (from
browser extensions or CDN-loaded CSS)
- This was reported via Sentry on production, occurring on any page when
logged in

## Changes
- **`frontend/instrumentation-client.ts`**: Added `ignoreErrors: [/Not
allowed to access cross-origin stylesheet/]` to `Sentry.init()` config

## Test plan
- [ ] Verify the error no longer appears in Sentry after deployment
- [ ] Verify Sentry Replay still works correctly for other errors
- [ ] Verify no regressions in error tracking (other errors should still
be captured)

<h2>Greptile Overview</h2>

<details><summary><h3>Greptile Summary</h3></summary>

Adds error filtering to Sentry client configuration to suppress
cross-origin stylesheet security errors that occur when Sentry Replay
(rrweb) attempts to serialize DOM snapshots containing stylesheets from
browser extensions or CDN-loaded CSS. This prevents noise in Sentry
error logs without affecting the capture of legitimate errors.
</details>


<details><summary><h3>Confidence Score: 5/5</h3></summary>

- This PR is safe to merge with minimal risk
- The change adds a simple error filter to suppress benign cross-origin
stylesheet errors that are caused by Sentry Replay itself. The regex
pattern is specific and only affects client-side error reporting, with
no impact on application functionality or legitimate error capture
- No files require special attention

This is the frontend for AutoGPT's next generation

🧢 Getting Started

This project uses pnpm as the package manager via corepack. Corepack is a Node.js tool that automatically manages package managers without requiring global installations.

For architecture, conventions, data fetching, feature flags, design system usage, state management, and PR process, see CONTRIBUTING.md. For Playwright and Storybook testing setup, see TESTING.md.

Prerequisites

Make sure you have Node.js 16.10+ installed. Corepack is included with Node.js by default.

Setup

1. Enable corepack (run this once on your system):

corepack enable

This enables corepack to automatically manage pnpm based on the packageManager field in package.json.

2. Install dependencies:

pnpm i

3. Start the development server:

Running the Front-end & Back-end separately

We recommend this approach if you are doing active development on the project. First spin up the Back-end:

# on `autogpt_platform`
docker compose --profile local up deps_backend -d
# on `autogpt_platform/backend`
poetry run app

Then start the Front-end:

# on `autogpt_platform/frontend`
pnpm dev

Open http://localhost:3000 with your browser to see the result. If the server starts on http://localhost:3001 it means the Front-end is already running via Docker. You have to kill the container then or do docker compose down.

You can start editing the page by modifying app/page.tsx. The page auto-updates as you edit the file.

Running both the Front-end and Back-end via Docker

If you run:

# on `autogpt_platform`
docker compose up -d

It will spin up the Back-end and Front-end via Docker. The Front-end will start on port 3000. This might not be what you want when actively contributing to the Front-end as you won't have direct/easy access to the Next.js dev server.

Subsequent Runs

For subsequent development sessions, you only need to run:

pnpm dev

Every time a new Front-end dependency is added by you or others, you will need to run pnpm i to install the new dependencies.

Available Scripts

  • pnpm dev - Start development server
  • pnpm build - Build for production
  • pnpm start - Start production server
  • pnpm lint - Run ESLint and Prettier checks
  • pnpm format - Format code with Prettier
  • pnpm types - Run TypeScript type checking
  • pnpm test - Run Playwright tests
  • pnpm test-ui - Run Playwright tests with UI
  • pnpm fetch:openapi - Fetch OpenAPI spec from backend
  • pnpm generate:api-client - Generate API client from OpenAPI spec
  • pnpm generate:api - Fetch OpenAPI spec and generate API client

This project uses next/font to automatically optimize and load Inter, a custom Google Font.

🔄 Data Fetching

See CONTRIBUTING.md for guidance on generated API hooks, SSR + hydration patterns, and usage examples. You generally do not need to run OpenAPI commands unless adding/modifying backend endpoints.

🚩 Feature Flags

See CONTRIBUTING.md for feature flag usage patterns, local development with mocks, and how to add new flags.

📙 Storybook

Storybook is a powerful development environment for UI components. It allows you to build UI components in isolation, making it easier to develop, test, and document your components independently from your main application.

Purpose in the Development Process

  1. Component Development: Develop and test UI components in isolation.
  2. Visual Testing: Easily spot visual regressions.
  3. Documentation: Automatically document components and their props.
  4. Collaboration: Share components with your team or stakeholders for feedback.

How to Use Storybook

  1. Start Storybook: Run the following command to start the Storybook development server:

    pnpm storybook
    

    This will start Storybook on port 6006. Open http://localhost:6006 in your browser to view your component library.

  2. Build Storybook: To build a static version of Storybook for deployment, use:

    pnpm build-storybook
    
  3. Running Storybook Tests: Storybook tests can be run using:

    pnpm test-storybook
    
  4. Writing Stories: Create .stories.tsx files alongside your components to define different states and variations of your components.

By integrating Storybook into our development workflow, we can streamline UI development, improve component reusability, and maintain a consistent design system across the project.
