# Python Sandbox SDK errors

> Error classes raised by the porter-sandbox Python Sandbox SDK

All SDK errors inherit from `SandboxError`.

```python theme={null}
from porter_sandbox import (
    AuthenticationError,
    NotFoundError,
    RateLimitError,
    SandboxError,
    ServerError,
)
```

## Error classes

| Error                 | Raised when                                           |
| --------------------- | ----------------------------------------------------- |
| `SandboxError`        | Base class for SDK-raised API errors.                 |
| `AuthenticationError` | The API rejects credentials.                          |
| `NotFoundError`       | A sandbox, volume, or other resource cannot be found. |
| `RateLimitError`      | The API returns a rate limit response.                |
| `ServerError`         | The API returns a server-side error.                  |

Each `SandboxError` includes:

| Attribute     | Type             | Description                           |
| ------------- | ---------------- | ------------------------------------- |
| `message`     | `str`            | Human-readable error message.         |
| `status_code` | `int \| None`    | HTTP status code, when available.     |
| `body`        | `object \| None` | Parsed response body, when available. |

## Handle errors

```python theme={null}
from porter_sandbox import Porter, SandboxError

with Porter() as porter:
    sandbox = porter.sandboxes.create(image="python:3.12-slim")

    try:
        result = sandbox.exec(["python", "-c", "raise SystemExit(2)"])
        if result.exit_code != 0:
            print(result.stderr)
    except SandboxError as exc:
        print(f"Sandbox API error: {exc.message}")
    finally:
        sandbox.terminate()
```

Non-zero command exit codes are returned in the exec response. They are normal command results, not SDK exceptions.
