Odata substringof错误

Question

我到处寻找，无法找到解决此错误的方法 我正在尝试在客户 webapi控制器上使用substringof。

URL：

http://mytestsite.com:54516/api/Customer?$filter=substringof(Name, 'pro')

我收到以下错误：

对我来说，似乎它插入了null而不是我在网址中使用的 pro 。

遇到此错误并知道该怎么做的任何人？

控制器：

<HttpGet, Queryable(AllowedQueryOptions:=AllowedQueryOptions.All,     HandleNullPropagation:=HandleNullPropagationOption.False, PageSize:=20)> _
Public Function GetValues(query As ODataQueryOptions(Of CustomerEntity)) As IEnumerable(Of CustomerModel.CustomerListModel)
    query.Validate(New ODataValidationSettings())

    Dim myModel As IQueryable(Of CustomerEntity)
    If CurrentUser.IsInRole("Customeradmin") Then
        myModel = CurrentUser.Region.Customers
    Else
        myModel = Repository.Query(Of CustomerEntity)()
    End If
    If (Not IsNothing(query.Filter)) Then
        myModel = query.Filter.ApplyTo(myModel, New ODataQuerySettings())
    End If
    If (Not IsNothing(query.OrderBy)) Then
        myModel = query.OrderBy.ApplyTo(myModel)
    End If

    Dim count = myModel.Count()

    If (Not IsNothing(query.Skip)) Then
        myModel = myModel.Skip(query.Skip.Value)
    End If
    If (Not IsNothing(query.Top)) Then
        myModel = myModel.Take(query.Top.Value)
    End If
    If (Not IsNothing(query.OrderBy)) Then
        myModel = query.OrderBy.ApplyTo(myModel)
    End If
    Dim res = myModel.Select(Function(c) New CustomerModel.CustomerListModel() With {
