ABP Framework version: v9.0.2
UI Type: Blazor Server

Tiered (for MVC) or Auth Server Separated (for Angular): no
Exception message and full stack trace: [13:30:09 ERR] Unhandled exception in circuit 'sA6sWJvu5si7aktFPlaAkqY76suTEm7JZ1k8lLRDScE'.

Steps to reproduce the issue: Add property to identityuser like in the documentation:

    ObjectExtensionManager.Instance.Modules()
    .ConfigureIdentity(identity =&gt;
    {
    identity.ConfigureUser(user =>
    {
    user.AddOrUpdateProperty\&lt;int?&gt;(
    "SupplierId",
    property =>
    {
    property.UI.Lookup.Url = "/api/app/suppliers";
    property.UI.Lookup.DisplayPropertyName = "companyName";
    }
    );
    });
    });

Create MyBlazorServerLookupApiRequestService.cs as mentioned in https://abp.io/support/questions/6195/Extension-property-in-Identity-Users-not-working-in-Azure When trying to access a modal which depends on the endpoint, you will get an null exception since HttpContext is null, remove the adding of headers according to this issue: https://abp.io/support/questions/8205/Extension-property-in-Identity-Users-not-working-in-Azure-6195 You will now get the loginpage as a result, instead of the json. How should we handle this to get access to the endpoint?
