heat.api.aws.exception module¶

Heat API exception subclasses - maps API response errors to AWS Errors.

exception heat.api.aws.exception.AlreadyExistsError(detail=None)[source]¶

Resource with the name requested already exists.

exception heat.api.aws.exception.HeatAPIException(detail=None)[source]¶

Bases: HTTPError

webob HTTPError subclass that creates a serialized body.

Subclass webob HTTPError so we can correctly serialize the wsgi response into the http response body, using the format specified by the request. Note this should not be used directly, instead use the subclasses defined below which map to AWS API errors.

code = 400¶

err_type = 'Sender'¶

explanation = 'Generic HeatAPIException, please use specific subclasses!'¶

Return a dict suitable for serialization in the wsgi controller.

This wraps the exception details in a format which maps to the expected format for the AWS API.
