def export_entities(program, project):

    Return a file with the requested entities as an attachment.

    Either ``ids`` or ``node_label`` must be provided in the parameters. When both are
    provided, ``node_label`` is ignored and ``ids`` is used.

    If ``ids`` is provided, all entities matching given ``ids`` will be exported. If
    there is only one entity type in the output, it will return a ``{node_type}.tsv`` or
    ``{node_type}.json`` file, e.g.: ``aliquot.tsv``. If there are multiple entity
    types, it returns ``gdc_export_{one_time_sha}.tar.gz`` for TSV format, or
    ``gdc_export_{one_time_sha}.json`` for JSON format. CSV is similar to TSV.

    If ``node_label`` is provided, it will export all entities of type with name
    ``node_label`` to a TSV file or JSON file. CSV is not supported yet in this case.

    Summary:
        Export entities

    Tags:
        export

    Args:
        program (str): |program_id|
        project (str): |project_id|

    Query Args:
        ids (str): one or a list of node IDs seperated by commas.
        node_label (str): type of nodes to look up, for example ``'case'``
        format (str): output format, ``json`` or ``tsv`` or ``csv``; default is ``tsv``
        with_children (str): whether to recursively find children or not; default is False
        category (str): category of node to filter on children. Example: ``clinical``
        without_id (bool): whether to include the ids in the export file; default is False

    Responses:
        200: Success
        400: Bad Request
        404: No id is found
        403: Unauthorized request.
