Errors

Custom exceptions for notion-sdk-py.

This module defines the exceptions that can be raised when an error occurs.

APIErrorCode

Bases: str, Enum

Error codes returned in responses from the API.

Source code in notion_client/errors.py

ConflictError = 'conflict_error' class-attribute instance-attribute

The transaction could not be completed, potentially due to a data collision. Make sure the parameters are up to date and try again.

InternalServerError = 'internal_server_error' class-attribute instance-attribute

An unexpected error occurred. Reach out to Notion support.

InvalidJSON = 'invalid_json' class-attribute instance-attribute

The request body could not be decoded as JSON.

InvalidRequest = 'invalid_request' class-attribute instance-attribute

This request is not supported.

InvalidRequestURL = 'invalid_request_url' class-attribute instance-attribute

The request URL is not valid.

ObjectNotFound = 'object_not_found' class-attribute instance-attribute

Given the bearer token used, the resource does not exist. This error can also indicate that the resource has not been shared with owner of the bearer token.

RateLimited = 'rate_limited' class-attribute instance-attribute

This request exceeds the number of requests allowed. Slow down and try again.

RestrictedResource = 'restricted_resource' class-attribute instance-attribute

Given the bearer token used, the client doesn't have permission to perform this operation.

ServiceUnavailable = 'service_unavailable' class-attribute instance-attribute

Notion is unavailable. Try again later. This can occur when the time to respond to a request takes longer than 60 seconds, the maximum request timeout.

Unauthorized = 'unauthorized' class-attribute instance-attribute

The bearer token is not valid.

ValidationError = 'validation_error' class-attribute instance-attribute

The request body does not match the schema for the expected parameters.
