How to use the normalizr.schema.Values function in normalizr

{
    idAttribute: (value, parent, sgName) => sgName,
    processStrategy: (value, parent, sgName) => {
      // We need to add a computed `id` attribute to the sshKey,
      // so we know the context of the key itself
      // e.g sitegroup = 'deploytest1' & sshKey = 'pat' => 'deploytest1/pat'
      // To maintain consistency with the yaml file content, we need to omit
      // the id attribute in the ssh key normalization process (see sshKey schema)
      const sshKeys = addSshKeyId('sitegroup', sgName, value.ssh_keys);

      return Object.assign({}, value, { ssh_keys: sshKeys });
    },
