      JSON specifying filter conditions.
      Accepts the same format as returned by the [queries](https://www.openproject.org/docs/api/endpoints/queries/) endpoint.
      Currently supported filters are:

      + sharing: filters versions by how they are shared within the server (*none*, *descendants*, *hierarchy*, *tree*, *system*).
    example: '[{ "sharing": { "operator": "*", "values": ["system"] }" }]'
