Error Handling

The SDK provides typed exceptions for different failure scenarios:

from documentstack import (
    DocumentStack,
    ValidationError,
    AuthenticationError,
    ForbiddenError,
    NotFoundError,
    RateLimitError,
    ServerError,
    TimeoutError,
    NetworkError,
)

try:
    result = client.generate("template-id", data={})
except ValidationError as e:
    # 400: Invalid request
    print(f"Validation failed: {e.message}")
except AuthenticationError as e:
    # 401: Invalid API key
    print(f"Authentication failed: {e.message}")
except ForbiddenError as e:
    # 403: No access to template
    print(f"Access forbidden: {e.message}")
except NotFoundError as e:
    # 404: Template not found
    print(f"Template not found: {e.message}")
except RateLimitError as e:
    # 429: Rate limit exceeded
    print(f"Rate limited. Retry after {e.retry_after} seconds")
except ServerError as e:
    # 500: Server error
    print(f"Server error: {e.message}")
except TimeoutError as e:
    # Request timed out
    print("Request timed out")
except NetworkError as e:
    # Network failure
    print(f"Network error: {e}")
