[facebook/react] Bug: View Deployment is not working across react.dev and i18n documentation

### ROOT CAUSE The "View Deployment" button is not functioning correctly because it is generating an incorrect Vercel URL. This is likely due to a bug in how the deployment URL is constructed, possibly involving a missing or incorrect deployment ID. The issue could be caused by either a typo in the code or an incorrect environment variable being used to build the URL. ### CODE FIX To fix this issue, we need to ensure that the "View Deployment" button correctly generates the appropriate Vercel URL. Here's how to implement the fix: 1. **Modify the Deployment URL Construction:** - **File:** `src/components/DeploymentPreviewButton.js` - **Change:** Update the URL construction to include the correct deployment ID. For example, if the deployment ID is stored in an environment variable, ensure it's being used correctly. 2. **Update the Environment Variables:** - **File:** `.env` - **Change:** Verify that the `DEPLOYMENT_ID` is correctly set in your environment variables. If it's missing, add it and ensure it's pointing to the correct Vercel project. 3. **Ensure Correct Integration with Vercel:** - **File:** `package.json` (if using Vercel CLI) - **Change:** Confirm that the Vercel CLI is properly configured with the correct project settings, including any necessary environment variables. ```javascript // Example of correct URL construction in DeploymentPreviewButton.js function DeploymentPreviewButton() { const deploymentId = process.env.DEPLOYMENT_ID; // Ensure this is correct const url = `https://${deploymentId}.vercel.app`; return window.location.href = url}>View Deployment; } ``` By implementing these changes, the "View Deployment" button will correctly redirect users to the appropriate Vercel deployment link.
