We have enable multi-tenancy in our application. In our application we need to display logo(custom logo uploaded by Tenant) on header as well as on some other pages. We have checked that there is one method "GetLogo()" in TenantCustomizationController. This controller exists in Web.Core project.
In "GetLogo()" method, tenantId is retrieved from AbpSession.GetTenantId(). And this tenantId will be passed to database for getting Image bytes from AbpBinaryObjects table. But in our system, we are getting AbpSession.GetTenantId()= null so logo (uploaded by Tenant) is not being displayed.
We are calling HeaderViewModel method "GetLogoUrl" which calls "GetLogo" from TenantCustomizationController. We are getting all values in LoginInformations.Tenant but not in TenantCustomizationController.
Please let us know how should we resolve this.

1)LoadStop.Web.MVC\Areas\App\Views\Shared\Components\AppDefaultBrand\Default.chtml
We have one "AppLogo" img tag with following src attribute on above page: src="@headerViewModel.GetLogoUrl(ApplicationPath, UiThemeCustomizer.IsTopMenuUsed || UiThemeCustomizer.IsTabMenuUsed ? UiThemeCustomizer.HeaderSkin: UiThemeCustomizer.LeftAsideAsideSkin)"
2)LoadStop.Web.MVC\Areas\App\Models\Layout\HeaderViewModel.cs
public string GetLogoUrl(string appPath, string menuSkin) { if (LoginInformations?.Tenant?.LogoId == null) { return appPath + $"Common/Images/app-logo-on-{menuSkin}.png"; }
//id parameter is used to prevent caching only. return appPath + "TenantCustomization/GetLogo?id=" + LoginInformations.Tenant.LogoId;}
3)LoadStop.Web.Core\Controllers\TenantCustomizationController.cs
[AllowAnonymous] public async Task<ActionResult> GetLogo() {
try { var tenant = await _tenantManager.GetByIdAsync(AbpSession.GetTenantId()); if (!tenant.HasLogo()) { return StatusCode((int)HttpStatusCode.NotFound); } var logoObject = await _binaryObjectManager.GetOrNullAsync(tenant.LogoId.Value); if (logoObject == null) { return StatusCode((int)HttpStatusCode.NotFound); } return File(logoObject.Bytes, tenant.LogoFileType); } catch (System.Exception ex) { Logger.Error("Catch-Exception in GetLogo: " + ex.Message); throw; }}
==========================================================================================
For our system, 3rd method "GetLogo" gets called and but AbpSession.GetTenantId()=null so it throws catch exception as per below: https://forum.aspnetboilerplate.com/viewtopic.php?p=21747
Above issue is same as my issue.
You can reproduce this issue on any of multi-tenancy enabled asp.net zero demo project where you can upload custom logo by tenant login and see that logo is being displayed on top left corner of header or not.

Hi,
I couldn't reproduce this on our demo (http://volosoft.demo.aspnetzero.com). Are you able to reproduce it on our live demo ?
Thanks,

For reproducing that issue we need to enable multitenancy. Could you please create one Tenant for this demo so we can test on that Tenant.
Thanks.

Hi @razkhan78
This is the login for the tenant named "Volosoft". So, you are seeing the tenant side of the app. When you go to settings page, you can see that you are able to select a logo.
