Replace non-existent `error` attribute for requests.Response object
Replace non-existent `error` attribute for requests.Response object

If an exception happens, during the update of a resource of a task, the attempt to log context
information (status of failed request) will lookup for a non-existent `error` attribute of a
`requests.Response` object . To fix this, we must replace with the `reason` attribute (provides
status text of HTTP response).
