After logging out, I implemented a process to move to the top page in the logged out state, and when I tried to log out, I got an error like the picture ...

There is no mistake in the code description There is no defect in the javascript description of the head ... If so, what is the cause of the error ...

I found an article that ** cannot be done with GET if the Http method of sign_out is DELETE.

Change Http method from DELETE to GET

Go to config / initializers / devise.rb. Then edit the value of config.sign_out_via from DELETE to GET.

config.sign_out_via = :get

When I ran it again after this edit, the error was fixed brilliantly ^ _ ^
