Error handling is crucial. Potential errors include invalid Base64 strings or issues with the `Blob` constructor. Wrap the conversion process in a `try...catch` block. You can use `try...catch` to handle errors during Buffer creation or Blob construction. Also, validate the Base64 string before attempting conversion to ensure it's a valid format. Example:
```javascript
function base64ToFileSafe(base64String, mimeType) {
try {
const buffer = Buffer.from(base64String, 'base64');
const file = new Blob([buffer], { type: mimeType });
return file;
} catch (error) {
console.error('Error converting Base64 to File:', error);
return null; // Or throw the error, depending on your needs
}
}
```
