.Net 10 Blazor Server Login in single page checkout

[Julien-Marpault]

Hello, I'm actually working on an e-commerce website.
The checkout page is a single page showing checkout steps one after other.
The first step is to signup or signin if not authenticated.

The user enters his username and password and submit.
Informations are submitted to SigninManager and I get this exception:
Unhandled exception rendering component: Headers are read-only, response has already started.

So I changed the way to access this page forcing reloading of the application in the navigationmanager in order to be in the same context as redirection to classic login page. The issue remains.

Is there a way to call this page to be int the same context than the login page and avoid the error ?

Thanks.
