Login action gives 401 error

[czepesch]

Hi there.
Sign up is working, I can check via console that user is created, but when I'm trying to log in there is:

12:51:53 web.1  | Started POST "/users/sign_in" for ::1 at 2022-06-17 12:51:53 +0200
12:51:53 web.1  | Processing by Devise::SessionsController#create as TURBO_STREAM
12:51:53 web.1  |   Parameters: {"authenticity_token"=>"[FILTERED]", "user"=>{"email"=>"[email protected]", "password"=>"[FILTERED]", "remember_me"=>"0"}, "commit"=>"Log in"}
12:51:53 web.1  |   User Load (6.9ms)  SELECT "users".* FROM "users" WHERE "users"."email" = $1 ORDER BY "users"."id" ASC LIMIT $2  [["email", "[email protected]"], ["LIMIT", 1]]
12:51:53 web.1  | Completed 401 Unauthorized in 423ms (ActiveRecord: 97.2ms | Allocations: 4083)

Is Readme is complete? Maybe some missing steps?
Thanks.
