NullReferenceException in Volo.Abp.AspNetCore.Components.Web.LeptonTheme.Components.ApplicationLayout.MainHeader.MainHeader

[sturlath]

Is there an existing issue for this?

• I have searched the existing issues

Description

Coming back to a open tab and refreshing I´m getting that error and no amount of F5 fixes the issue. The only thing possible is to clear all application data (totally not something a normal user is expected to do)

The issue seems to be in code handling of "Volo.Abp.AspNetCore.Components.Web.LeptonTheme.Components.ApplicationLayout.MainHeader.MainHeader.Dispose()"

 Unhandled exception rendering component: Object reference not set to an instance of an object.
System.NullReferenceException: Object reference not set to an instance of an object.
   at Volo.Abp.AspNetCore.Components.Web.LeptonTheme.Components.ApplicationLayout.MainHeader.MainHeader.Dispose()
   at Microsoft.AspNetCore.Components.Rendering.ComponentState.DisposeAsync()

Full log. As you can see the user seem to be no longer with valid credentials.

Then probably because of that error few other errors follow

Reproduction Steps

N/A but you should at least look at the code that is throwing the NullReferenceException and prevent that!

Expected behavior

If the user no longer has valid credentials he/she should be routed to a login page or the a refresh token mechanishm should kick in.

Actual behavior

The page becomes useless!

Regression?

First time I´m seeing this after updating to 8.2.x

Known Workarounds

Nuke the application data in the browser.. not viable

Version

8.2.2

User Interface

Blazor Server

Database Provider

EF Core (Default)

Tiered or separate authentication server

Tiered

Operation System

Windows (Default)

Other information

I sure hope you harden this code part in 8.2.3!

@EngincanV @maliming no feedback on this? Unfortunatly I can´t create a demo code using the pro version to share with you...

[sturlath]

I have figured out that this only happens when I F5 the page but if I navigate to it by menu this doesn´t happen. 🤷‍♂️

[sturlath]

I have been trying to figure this out but I can see anything else than the MainHeader.cs needs to add some IsDisposed/nullreference-check logic..

Correct me if I´m wrong here...

Anything I can try out or change/override/etc?

[maliming]

You'd better share a project that can reproduce the problem. This way we can find the cause as quickly as possible

🤷‍♂️no idea how I can do that without having access to the pro version.. but I guess somebody else will hit this when they update to newest Blazorise using Lepton on Blazor Server... I will consider downgrading...

Hey there. I see that this issue is closed but I don't see what was the solution. I'm facing the same problem as shown below.

It's weird because the error seems to happen at random (about 50% of the times) when refreshing the login screen. I tried different Blazorise versions without success. I'm on ABP 8.3.2.

[maliming]

hi

I have reproduced the problem. I will fix this in 8.3.3.
