I am using AspNetCore.OData 8.2.5 and .net6 Api
Have a dbcontext entity as Product, On top of Product i have a json converter which is not working as expected like
From Product entity response i want to concate the properties

`[JsonConverter(typeof(ProductDataConverter))]
public class Product
{
public int Id { get; set; }
public string Name { get; set; }

public List<DataRow> Data { get; set; }
public string Schema { get; set; }

}

public class DataRow
{
public int Id { get; set; }
public int ProductId { get; set; }
public string Data { get; set; }
}`

my api will be
`public async Task Get(string dataSourceName, ODataQueryOptions options)
{

//var dataSource = await _productDataService.GetDataProductByQuery(dataSourceName).FirstAsync();
var dataSource = await ApplyODataQuery(dataSourceName, options).FirstOrDefaultAsync();         



return Ok(dataSource);

}

private IQueryable ApplyODataQuery(string dataSourceName, ODataQueryOptions options)
{
IQueryable dataSource = _productDataService.GetDataSourceByQuery(dataSourceName).IgnoreAutoIncludes();
var result = options.ApplyTo(dataSource);
return result.Cast();
}`

When i execute this code then i am getting the below exception
"Error": {
"Code": 500,
"Message": "Token PropertyName in state Property would result in an invalid JSON object. Path 'Container.Value[0].Instance'."
}

Any help would be appreciate, i tried many ways but nothing is working out, Once we execute the db query if i see the result it showing as AspNetCore.SelectAllExpand with out converter i am able to get the data as expected but if i register that converter then it's not working

Can you elaborate a bit more on this? What does your converter to, and why do you need a converter in the first place?
