Асинхронная вставка Linq2Db — невозможно получить доступ к удаленному объекту. ObjectDispose_ObjectName_Name' ⇐ C#

[Anonymous]

Я работаю над собственным проектом, для которого использую .NET Core 3.1 и инструмент ORM Linq2b. У меня проблема со вставкой данных с помощью асинхронного метода. Я хочу вставить данные журнала. В Linq2Db есть метод InsertWithInt32IdentityAsync. Этот метод возвращает ошибку:

Невозможно получить доступ к удаленному объекту. Имя объекта: IServiceProvider.

Вот реализации.

    [HttpPost("createpost")]
[Authorize]
public virtual async Task CreatePost([FromForm] PostCreateApi model)
{
var serviceResponse = _postService.Create(model);

if (serviceResponse.Warnings.Count > 0 || serviceResponse.Warnings.Any())
return BadResponse(new ResultModel
{
Status = false,
Message = serviceResponse.Warnings.First()
});

//Here returns an error
await _logService.InsertLogAsync(Domain.Enumerations.LogLevel.Information, $"PostsController- Create Post Request", JsonConvert.SerializeObject(model));

return OkResponse(new PostListDto
{
Id = serviceResponse.Data.Id,
Text = serviceResponse.Data?.Text,
ImageUrl = serviceResponse.Data.ImageUrl?.ToString(),
CreatedByUserName = serviceResponse.Data?.CreatedByUserName,
CreatedByUserPhoto = serviceResponse.Data?.CreatedByUserPhoto,
CreatedDate = serviceResponse.Data.CreatedDate,
VideoUrl = serviceResponse.Data?.VideoUrl,
PostType = serviceResponse.Data?.PostType,
Comments = null
});
}

Вот метод InsertLogAsync.

 public virtual async Task InsertLogAsync(LogLevel logLevel, string shortMessage, string fullMessage = "", AppUser appUser = null)
{
var log = new Log
{
LogLevel = logLevel,
ShortMessage = shortMessage,
FullMessage = fullMessage,
IpAddress = _webHelper.GetCurrentIpAddress(),
CustomerId = appUser?.Id,
PageUrl = _webHelper.GetThisPageUrl(true),
ReferrerUrl = _webHelper.GetUrlReferrer(),
CreatedDate = DateTime.UtcNow
};

await _logRepository.InsertAsync(log);

return log;
}

Вот метод BaseDataProvider InsertEntityAsync.

  public virtual async Task  InsertEntityAsync(TEntity entity) where TEntity :
BaseEntity
{
using var dataContext = CreateDataConnection();
entity.Id = await dataContext.InsertWithInt32IdentityAsync(entity);
return entity;
}
