I get error when I add or update Data grid with Odata

[Ivan]

I have data grid with Odata and ODataV4Adaptor and i get all data but when I add or edit item i get this error 

"This JsonSerializerOptions instance is read-only or has already been used in serialization or deserialization."

This is my grid: "

    <SfGrid ID="Grid" TValue="Scout" AllowPaging="true" AllowFiltering="true" Toolbar="@(new List<string>() { "Add", "Edit", "Delete", "Cancel", "Update" })">

        <GridSearchSettings IgnoreCase="true"></GridSearchSettings>

        <GridEvents TValue="Scout" OnActionFailure="ActionFailureHandler"></GridEvents>

        <SfDataManager Url="@DataAdress" Adaptor="Adaptors.ODataV4Adaptor"></SfDataManager>

        <GridEditSettings AllowAdding="true" AllowEditing="true" AllowDeleting="true" Mode="EditMode.Normal"></GridEditSettings>

    <GridColumns>

        <GridColumn Field=@nameof(Scout.Id) Visible="false" HeaderText="Scout ID" IsIdentity="true" IsPrimaryKey="true" TextAlign="TextAlign.Right" Width="20"></GridColumn>

            <GridColumn Field=@nameof(Scout.Name) HeaderText="Scout Name" TextAlign="TextAlign.Left" Width="150"></GridColumn>

        <GridColumn Field=@nameof(Scout.ScoutingOrganization) HeaderText="Organization" Type="ColumnType.String" TextAlign="TextAlign.Left" Width="150"></GridColumn>

    </GridColumns>

</SfGrid>

"

Code behind : "

        private string DataAdress = "";

        protected override void OnInitialized()

        {

            DataAdress = "https://localhost:7238/odata/Scout";

        }

        public void ActionFailureHandler(FailureEventArgs args)

        {

            var nesto = args;

        }

        public class Scout

        {

            public int Id { get; set; }

            public string? Name { get; set; }

            public string? ScoutingOrganization { get; set; }

        }
