    Hi @bruno93

    Normally uploaded files are saved to database and retrieved when you click the link. Are you using latest version of AspNet Zero ? I couldn't reproduce this problem on latest version and on our demo http://volosoft.demo.aspnetzero.com/.

    Hello @bruno93

    The problem is about multitenancy, Multitenancy is disabled in your application.

    ChatControllerBase UploadFile saves files with setting tenant id null

    https://github.com/aspnetzero/aspnet-zero-core/blob/073ce19a29cb6a4645266b7a6889d316b99dfc55/aspnet-core/src/MyCompanyName.AbpZeroTemplate.Web.Core/Controllers/ChatControllerBase.cs#L50-L53

    using (CurrentUnitOfWork.SetTenantId(null))
{
    await BinaryObjectManager.SaveAsync(fileObject);
}

    But it stores it with default tenant's id in db.

    And then ChatController GetUploadedObject queries it with setting tenant id null again. But this time it realt work with tenant id null and that's why it can not find it. https://github.com/aspnetzero/aspnet-zero-core/blob/073ce19a29cb6a4645266b7a6889d316b99dfc55/aspnet-core/src/MyCompanyName.AbpZeroTemplate.Web.Host/Controllers/ChatController.cs#L21

    using (CurrentUnitOfWork.SetTenantId(null))
{
    var fileObject = await BinaryObjectManager.GetOrNullAsync(fileId);
    if (fileObject == null)
    {
        return StatusCode((int)HttpStatusCode.NotFound);
    }

    return File(fileObject.Bytes, contentType, fileName);
}

    I created an issue abouot it. (https://github.com/aspnetzero/aspnet-zero-core/issues/3305) We will investigate the situation that caused this error. Until that, you can change

    -using (CurrentUnitOfWork.SetTenantId(null))
+using (CurrentUnitOfWork.SetTenantId(1))
{
    var fileObject = await BinaryObjectManager.GetOrNullAsync(fileId);
