I have implemented a login form that utilizes the login controller, which serves as a base controller. While the controller functions properly, my concern lies with error handling. Regrettably, I am unable to display error messages within the form as there is no means to return error messages from the controller. I would greatly appreciate any assistance in resolving this issue.

I am new to .NET and currently working on building an app using clean architecture and Blazor components/pages. I have a solution with two projects: one for executing the app (Main) and the other for the layouts (components/pages/code, etc.).
