How to use the filepond.FileOrigin.LOCAL function in filepond

const fileValueToMutationValue = function(value) {

    // File is already uploaded, we just need to return the uuid of the file for unite.
    if(value.origin === FileOrigin.LOCAL) {
      return value.serverId;
    }

    // File is a new input, so we need to pass the upload token, created by unite cms.
    else if(value.origin === FileOrigin.INPUT) {
      return value.getMetadata('uniteInformation').token;
    }

    throw "Invalid file origin";
  };
