### Step 5: return the content { #step-5-return-the-content }

{* ../../docs_src/first_steps/tutorial001.py hl[8] *}

You can return a `dict`, `list`, singular values as `str`, `int`, etc.

You can also return Pydantic models (you'll see more about that later).

    transformer.setMaxContentSize(10 * 1024 * 1024); // 10MB limit
});
```

## Troubleshooting

### Common Issues

#### Connection Timeouts
```java
// Increase timeout values
client.setConnectionTimeout(60000);  // 60 seconds
client.setSocketTimeout(120000);     // 120 seconds
```

#### Memory Issues
```java
// Reduce concurrent threads and batch sizes

        // Get an item
        OptionalEntity<CharMappingItem> item1 = charMappingFile.get(1L);
        assertTrue(item1.isPresent());

        // Modify the same item with different values
        CharMappingItem updateItem1 = item1.get();
        updateItem1.setNewInputs(new String[] { "m", "n" });
        updateItem1.setNewOutput("o");

        // Create another update for the same item

Common examples of CPU bound operations are things that require complex math processing.

For example:

* **Audio** or **image processing**.
* **Computer vision**: an image is composed of millions of pixels, each pixel has 3 values / colors, processing that normally requires computing something on those pixels, all at the same time.
