I have a filter:

1. filters: Array[3]
   
   1. 0: AttributeFilter
      
      1. attributeName: “folderId”
      2. matchFlag: “EXACTLY”
      3. matchValue: “10”
      4. __proto__: CallbackObject
   2. 1: AttributeFilter
      
      1. attributeName: “folderId”
      2. matchFlag: “EXACTLY”
      3. matchValue: “20”
      4. __proto__: CallbackObject
   3. 2: AttributeFilter
      
      1. attributeName: “folderId”
      2. matchFlag: “EXACTLY”
      3. matchValue: “22”
      4. __proto__: CallbackObject
   4. length: 3
   5. __proto__: Array[0]
2. type: “UNION”
3. __proto__: CallbackObject

Trying to get messages:

service.messageStorage.findMessages( f, function(m) { console.dir(m); }, function(e) { console.dir(e); });

get the following error:

1. code: 0
2. message: “Argument is invalid”
3. name: “InvalidValuesError”
4. type: “InvalidValuesError”
5. __proto__: CallbackObject

Which argument is invalid?
