Error message : "unable to parse the search query"

[Giulia]

Hello,
Ok, each time I launch back after closing the Zimbra Desktop, I have this error message :

method:	SearchRequest
msg:	Couldn't parse query: is :unread
code:	mail.QUERY_PARSE_ERROR
detail:	soap:Sender

Body: {
  SearchRequest: {
    _jsns: "urn:zimbraMail",
    limit: 100,
    locale: {
      _content: "en_US"
     },
    offset: 0,
    query: "is :unread",
    sortBy: "dateDesc",
    types: "conversation",
    tz: {
      id: "(GMT+01.00) Amsterdam / Berlin / Bern / Rome / Stockholm / Vienna"
     }
   }
 },
Header: {
  context: {
    _jsns: "urn:zimbra",
    account: {
      _content: "giulia2213@yahoo.com",
      by: "name"
     },
    authToken: "(removed)",
    format: {
      type: "js"
     },
    sessionId: {
      _content: 1167,
      id: 1167
     },
    userAgent: {
      name: "ZimbraWebClient - PRISM (Win)",
      version: "0.0"
     }
   }
 }

So what is the solution to solve my problem ?
