How to sign out over HttpContext in server-side Blazor

I access the HttpContext in a Blazor server-side view to manually log out. I added this line to Startup.cs: services.AddHttpContextAccessor(); and inject it in the view with @inject IHttpContextAccessor HttpContextAccessor.I've got a log out button which tries to execute this code:

await HttpContextAccessor.HttpContext.SignOutAsync("Cookies");

but I get the following error message:

System.InvalidOperationException: 'Headers are read-only, response has already started.'

How can I prevent this error?
