ApiError

This exception represents errors returned by the Fiddler platform API, including both client errors (4xx status codes) and server errors (5xx status codes). It contains detailed information about the error including the HTTP status code, error message, and any additional error details provided by the API. ApiError serves as the base class for more specific API errors like NotFound and Conflict, but can also be raised directly for other HTTP error status codes. You won’t see HTTP 429 or most 5xx codes here: the client retries those itself and, when it gives up, raises a plain BaseError instead.

Examples

Handling general API errors:

try:
    model = fdl.Model.from_name(name="my-model", project_id=project.id)
except fdl.ApiError as e:
    print(f"API Error {e.code}: {e.message}")
    if e.errors:
        print(f"Details: {e.errors}")

Handling specific status codes:

try:
    model = fdl.Model.from_name(name="my-model", project_id=project.id)
except fdl.ApiError as e:
    if e.code in (401, 403):
        print("Check your token and its permissions")
    else:
        print(f"API error {e.code}: {e.message}")
