## Troubleshooting

### Common Issues

#### Connection Timeouts
```java
// Increase timeout values
client.setConnectionTimeout(60000);  // 60 seconds

        TestTransformer transformer = new TestTransformer("largeDataTransformer");

        // Create large response data
        byte[] largeBody = new byte[10 * 1024 * 1024]; // 10MB
        for (int i = 0; i < largeBody.length; i++) {
            largeBody[i] = (byte) (i % 256);
        }

        ResponseData responseData = new ResponseData();

        Files.createDirectory(dir3);
        Files.writeString(dir3.resolve("file4.txt"), "file4");

        // Setup public directory files
        byte[] largeContent = new byte[10 * 1024 * 1024]; // 10MB
        for (int i = 0; i < largeContent.length; i++) {
            largeContent[i] = (byte) (i % 256);
        }
        Files.write(publicDir.resolve("largefile.bin"), largeContent);
