Entity Framework Core PostgreSQL json query

问题

Always return empty results

var collection = await _context.Settings
.Select(s => new
{
    s.SettingId,
    s.SettingParentId,
    SettingValue = s.SettingValue.GetProperty(lang)
})
.Where(s => EF.Functions.JsonExists(s.SettingValue, lang))
.ToListAsync();

I try return only key from json but always return empty, when remove "select" works fine but i need only one key

This is the model

public class Setting
{
    public string SettingId { get; set; }
    public string SettingParentId { get; set; }
    public JsonElement SettingValue { get; set; }
}
