Errors

SOURCE_API

SOURCE_API = "DAYTONA_API"

Wire-format source identifier for errors originating from the Daytona API. source = None means the response did not carry a structured envelope (treat as opaque).

SOURCE_DAEMON

SOURCE_DAEMON = "DAYTONA_DAEMON"

Wire-format source identifier for errors originating from the sandbox daemon (toolbox).

SOURCE_PROXY

SOURCE_PROXY = "DAYTONA_PROXY"

Wire-format source identifier for errors originating from the Daytona proxy.

DaytonaError

class DaytonaError(Exception)

Base error for Daytona SDK.

Example:

try:
    sandbox = daytona.get("missing-sandbox")
except DaytonaError as exc:
    print(exc.status_code)
    print(exc.code)
    print(exc.message)

Attributes:

message str - Error message
status_code int | None - HTTP status code (set only for errors translated from an HTTP response; None for client-side errors).
code str | None - Machine-readable error code from the server envelope (None for client-side errors).
source str | None - Originating service. None when the response did not carry a structured envelope. Otherwise one of :data:SOURCE_API, :data:SOURCE_DAEMON, :data:SOURCE_PROXY.
headers dict[str, Any] - Response headers (empty for client-side errors).

DaytonaError.init

def __init__(message: str,
             status_code: int | None = None,
             headers: Mapping[str, Any] | None = None,
             code: str | None = None,
             source: str | None = None)

Initialize Daytona error.

Arguments:

message str - Error message
status_code int | None - HTTP status code if the error came from a Daytona service response.
headers Mapping[str, Any] | None - Response headers if available
code str | None - Machine-readable error code from the wire envelope
source str | None - Originating service from the wire envelope. Left as None for SDK-side errors and for responses from services that don't emit the envelope.

DaytonaError.error_code

@property
def error_code() -> str | None

Deprecated alias of :attr:code, kept for backward compatibility.

DaytonaNotFoundError

class DaytonaNotFoundError(DaytonaError)

Error for when a resource is not found (HTTP 404).

Example:

try:
    sandbox.fs.download_file("/workspace/missing.txt")
except DaytonaNotFoundError as exc:
    print(exc.status_code)

DaytonaAuthenticationError

class DaytonaAuthenticationError(DaytonaError)

Error for when authentication fails (HTTP 401).

Example:

try:
    for sandbox in daytona.list():
        print(sandbox.id)
except DaytonaAuthenticationError as exc:
    print(exc.status_code)

DaytonaForbiddenError

class DaytonaForbiddenError(DaytonaError)

Error for when the request is forbidden (HTTP 403).

Example:

try:
    daytona.get("sandbox-without-access")
except DaytonaForbiddenError as exc:
    print(exc.message)

DaytonaRateLimitError

class DaytonaRateLimitError(DaytonaError)

Error for when rate limit is exceeded (HTTP 429).

Example:

try:
    for sandbox in daytona.list():
        print(sandbox.id)
except DaytonaRateLimitError as exc:
    print(exc.code)

DaytonaConflictError

class DaytonaConflictError(DaytonaError)

Error for when a resource conflict occurs (HTTP 409).

Example:

try:
    params = CreateSandboxFromSnapshotParams(name="existing-sandbox")
    daytona.create(params)
except DaytonaConflictError as exc:
    print(exc.code)

The deprecated DaytonaValidationError alias remains for older callers that historically grouped both HTTP 400 and HTTP 422 validation failures under one name. New code should catch DaytonaBadRequestError and DaytonaUnprocessableEntityError explicitly.

Example:

try:
    Image.debian_slim("3.8")
except DaytonaBadRequestError as exc:
    print(exc.message)

DaytonaTimeoutError

class DaytonaTimeoutError(DaytonaError)
