Files from project still don't solve the problem. Best Regards and Have a nice Coding! :)

I think I have found the solution of this issue...! :-) I had to take it back a bit to /api/schema.js I deleted the !"username"! from type Mutation - signIn
This seemed logical because we do not have such a field in signin.js file in web/solutions/04-Authentication-State/pages/signin.js / GraphQL requires you to be explicit about specifying which fields you would like returned from your query. Am I right? Now everything works great so far ...I can log in and log out and application does not break :) I wanted to make a "pull request" but I'm ashamed ... Please analyse my code and grant permission for a "pull request" if everything works fine...?!? See You Soon and Have a nice Day or Night whatever you want;)
