Contains predicate is not working for LookupMulti fields

Entity class:
`

   /// <summary>
    ///  Содержание мероприятий 
    ///  
    ///  List27List
    /// </summary>
    [SharepointList("Содержание мероприятий")]
    public partial class EventContent : ISharepointItem
    {

        [SharepointField("ID")]
        public int Id { get; set; } //ID:Counter ,

        [SharepointField("MontBlocks", MapData.LookupValue)]
        public List<String> MontBlocks { get; set; }

    }//Содержание мероприятий

Mapping is ok:

    [TestMethod]
    public void TestMethod4()
    {
        List<EventContent> eventContents = _sharepointClient.GetAll<EventContent>();
        }

But where query fails
Test:

  [TestMethod]
        public void TestMethod3()
        {
            var ecc= _sharepointClient.Query<EventContent>(ec => ec.MontBlocksId.Contains(1)).FirstOrDefault();
          
        }

with:

{CamlexNET.NonSupportedOperandTypeException: Operand type 'System.Collections.Generic.List1[System.Int32]' is not supported at CamlexNET.Impl.Factories.OperandBuilder.CreateValueOperand(Type type, Object value, Boolean includeTimeValue, Boolean parseExactDateTime, Boolean isComparisionOperation, Boolean isIntegerForUserId) at CamlexNET.Impl.Factories.OperandBuilder.createValueOperand(Type type, Object value, Expression expr) at CamlexNET.Impl.Factories.OperandBuilder.createValueOperandFromConstantExpression(ConstantExpression expr, Type explicitOperandType, Expression sourceExpr) at CamlexNET.Impl.Factories.OperandBuilder.CreateValueOperandForNativeSyntax(Expression expr, Type explicitOperandType, Expression sourceExpr) at CamlexNET.Impl.Factories.OperandBuilder.CreateValueOperandForNativeSyntax(Expression expr, Type explicitOperandType) at CamlexNET.Impl.UnaryExpressionBaseAnalyzer.getValueOperand(LambdaExpression expr) at CamlexNET.Impl.Operations.Contains.ContainsAnalyzer.GetOperation(LambdaExpression expr) at CamlexNET.Impl.GenericTranslator.TranslateWhere(LambdaExpression expr) at CamlexNET.Impl.Query.Where(Expression1 expr)

This code working:
`
string camelQuery =Camlex.Query().Where(x => (x["MontBlocks"] == (DataTypes.LookupMultiId) id.ToString())).ToString();
EventContent eventContent = spEventContentRepository.Query(camelQuery).FirstOrDefault();
