How to Fix Figma Weave SDK Integration Errors

Diagnose Figma Weave SDK Integration Failures

Figma Weave SDK integration errors typically occur during the initial handshake, client configuration, or when compiling project dependencies. If your application fails to initialize the Figma Weave SDK, throws unhandled promise rejections, or drops connections silently, follow this step-by-step troubleshooting guide to restore functionality.

This independent guide provides technical steps to isolate and resolve integration problems.

Step 1: Check Node.js and SDK Version Compatibility

Outdated SDK versions or incompatible runtime environments are a common source of silent integration failures.

1. Check your Node.js runtime version: Ensure your environment meets the minimum version required by the Figma Weave SDK (typically Node.js 18.x or higher). Run node -v in your terminal to verify. 2. Inspect your package.json: Verify that the @figma/weave (or your specific SDK package name) is correctly listed in your dependencies. 3. Perform a clean install: Sometimes, cached dependencies or yarn/npm lockfile conflicts block proper installation. Clear your cache and reinstall: `bash # For npm users rm -rf node_modules package-lock.json npm cache clean --force npm install

For Yarn users rm -rf node_modules yarn.lock yarn cache clean yarn install ``` 4. **Check for deprecated methods:** If you recently updated the SDK, review the official changelog. Functions or initialization parameters may have been deprecated or restructured.

Step 2: Validate the SDK Initialization Block

An incorrect initialization syntax will prevent the SDK from instantiating the client object, resulting in undefined errors when you attempt to make API calls.

1. Locate your initialization code: This is typically found in your main entry file (such as index.js, app.ts, or a dedicated configuration file). 2. Ensure correct parameter structure: Check that you are passing the required configuration object. A standard initialization should look similar to this: `javascript import { FigmaWeaveClient } from '@figma/weave-sdk';

const weave = new FigmaWeaveClient({ apiKey: process.env.FIGMA_WEAVE_API_KEY, environment: 'production', // or 'sandbox' timeout: 10000 // 10 seconds timeout limit }); ` 3. Check for synchronous environment variable loading: If you load your API key from a .env file, ensure that your configuration manager (like dotenv) is initialized *before* you instantiate the Figma Weave client. If the key loads too late, the SDK initializes with an undefined credential.

Step 3: Configure CORS and Network Proxies

If the SDK is running in a browser environment or a restricted server network, browser security policies or firewalls can block outgoing requests.

1. Verify CORS headers: If you are calling the SDK from a client-side web application, check your browser's developer console for Cross-Origin Resource Sharing (CORS) blocks. If present, route your Weave SDK calls through a secure backend proxy rather than exposing your credentials and making direct browser-to-API calls. 2. Check corporate firewalls and VPNs: Highly restricted corporate networks often block traffic to external APIs. Temporarily disconnect from your corporate VPN or switch to an open network to isolate if local network policies are blocking the SDK's outbound connections. 3. Configure proxy support in the SDK: If your environment requires a proxy, check the SDK documentation for proxy configuration settings or use an HTTPS agent to route the traffic: `javascript import HttpsProxyAgent from 'https-proxy-agent';

const weave = new FigmaWeaveClient({ apiKey: process.env.FIGMA_WEAVE_API_KEY, httpAgent: new HttpsProxyAgent(process.env.PROXY_URL) }); `

Step 4: Implement Proper Error Catching and Logging

Silent failures occur when the SDK rejects a promise but the application code lacks a .catch() block or a try/catch wrapper to log the issue.

1. Wrap your SDK calls in try/catch blocks: `javascript async function initializeWeaveConnection() { try { const session = await weave.initializeSession(); console.log('Weave session initialized successfully:', session.id); } catch (error) { console.error('Figma Weave SDK failed to initialize:', error.message); console.error('Error Code:', error.code); console.error('Network Details:', error.response?.data); } } ` 2. Inspect the exact error payload: The SDK often returns a rich error object containing error.code or error.response. If you see a 400 Bad Request or 422 Unprocessable Entity, the issue is with the payload schema rather than the integration itself.

When to Escalate

If the SDK still fails to integrate after updating dependencies, verifying initialization syntax, and resolving network barriers:

1. Consult developer forums: Look for open issues relating to your specific SDK version on GitHub or community boards.
2. Verify your Figma developer account status: Ensure your developer account has active API access privileges and that the API keys you generated are approved for Weave services.
3. Submit a bug report: Contact Figma developer support via your developer portal. Be sure to provide your Node/runtime environment version, the exact version of the SDK, and a sanitized copy of your initialization configuration and error stack trace.
