Required. The bucket used in 'output_uri_prefix' must exist and there must
be no files under 'output_uri_prefix'. 'output_uri_prefix' must end with
"/" and start with "gs://". One 'output_uri_prefix' can only be used by one
batch translation job at a time. Otherwise an INVALID_ARGUMENT (400) error
is returned.
