To handle potential errors during synchronous file writing, you should wrap the `fs.writeFileSync()` call within a `try...catch` block. This allows you to gracefully handle exceptions like permission errors or invalid file paths. For example: `try { fs.writeFileSync('data.json', JSON.stringify(data)); } catch (err) { console.error('Error writing JSON to file:', err); }`.
