I am getting error 500 on facebook login callback on production with asp.net core 2.2 application

Question

My issue mainly appear only after deployment the application on smarterasp.net hosting.

when trying to login to facebook it redirect me to the facebook then after i accept the permissions required on return back to the app am getting the 500 error page on .../Identity/Account/ExternalLogin?handler=Callback# =

I tried to see the log but no log appears even after creating the logs folder manually.

i trying to make some changes on webconfig such as in-process to out-process but nothing works.

the issue is coming after the OnPost() when returning OnGetCallbackAsync().

   public IActionResult OnPost(string provider, string returnUrl = null)
        {
            // Request a redirect to the external login provider.
            var redirectUrl = Url.Page("./ExternalLogin", pageHandler: "Callback", values: new { returnUrl });
            var properties = _signInManager.ConfigureExternalAuthenticationProperties(provider, redirectUrl);
            return new ChallengeResult(provider, properties);
        }

  public async Task<IActionResult> OnGetCallbackAsync(string returnUrl = null, string remoteError = null)
    {
        returnUrl = returnUrl ?? Url.Content("~/");
        if (remoteError != null)
        {
            ErrorMessage = $"Error from external provider: {remoteError}";
            return RedirectToPage("./Login", new {ReturnUrl = returnUrl });
        }
        var info = await _signInManager.GetExternalLoginInfoAsync();
        if (info == null)
        {
            ErrorMessage = "Error loading external login information.";
            return RedirectToPage("./Login", new { ReturnUrl = returnUrl });
        }

        // Sign in the user with this external login provider if the user already has a login.
        var result = await _signInManager.ExternalLoginSignInAsync(info.LoginProvider, info.ProviderKey, isPersistent: false, bypassTwoFactor : true);
        if (result.Succeeded)
        {
            _logger.LogInformation("{Name} logged in with {LoginProvider} provider.", info.Principal.Identity.Name, info.LoginProvider);
            return LocalRedirect(returnUrl);
        }
        if (result.IsLockedOut)
        {
            return RedirectToPage("./Lockout");
        }
        else
        {
            // If the user does not have an account, then ask the user to create an account.
            ReturnUrl = returnUrl;
            LoginProvider = info.LoginProvider;
            if (info.Principal.HasClaim(c => c.Type == ClaimTypes.Email))
            {
                Input = new InputModel
                {
                    Email = info.Principal.FindFirstValue(ClaimTypes.Email)
                };
            }
            return Page();
        }
    }

没问题，但是我发布的内置文件有些未完成，有些控制器正在缓存参数，但是从Facebook重定向后，缓存就被清除了，并且出现了问题。
