With my Blazor application, I am hitting a REST API endpoint that produces both streaming and non-streaming results, depending on the endpoint I hit. The non-streaming endpoint is just standard JSON:

I am trying to build a minimal working example of a CircuitHandler in a Blazor server side application but none of the CircuitHandler methods are called. I feel like I’m missing something obvious.

Blazor Server .NET 8.

I have a Blazor server-side app, which simulates a windowing system. This uses the TelerikWindow component. Each child window is a separate component, inheriting from a WindowBase component and containing the code for the specific window.

I have Blazor pages that are structured like so:

We have one user this is happening with. We cannot reproduce it and it is not happening to any others. And it has happened to them twice out of 8 uses of the relevant page. Needless to say, I can’t create a MVE because we can’t reproduce it.

This is a Blazor Server solution. The PopulateFilmography() method sets a callback method in the FilmographyService class and then calls filmographyService.GetFilmography.
That service method gets data from an API and loops through the results. In each loop iteration, it calls the callback method. This method displays a modal (if not already open) and adds log entry to its data source. The idea is that the modal will display the activity of the API calls in real time.

I am load testing my blazor app. As the load test was running I loaded a page myself with F12 displaying in my browser and see this (it consistently happens):

I have converted my Blazor Server-side Application to the new Blazor Web App project. Everything works as expected except for when I navigate to a view that does not exist.
