enum (Format)

Required. File format in which the labels will be exported.
objectUri

string

Required. The Google Cloud Storage URI to write the feedback labels to. The file name will be used as a prefix for the files written to the bucket if the output needs to be split across multiple files, otherwise it will be used as is. The file extension will be appended to the file name based on the format selected. E.g. gs://bucket_name/object_uri_prefix
addWhitespace
