I'm checking the code on rubycop while creating a portfolio on rails,
Espec/requests/users_requests_spec.rb: 97: 1: E: Lint/Syntax: unexpected token kEND
(Using Ruby 2.6 parser;configure using TargetRubyVersion parameter, under AllCops)
end
^^^
Error was coming out.

I'll sort out what I doubt or don't understand.
1. Possibility of syntax error
2. Misconfiguration of rubycop.yml and ruby-version
3. I don't know how to ensure that the specified version is adopted
(I can't verbalize well when I look it up on the net)

It doesn't look syntactically wrong,
The terget ruby ​​version of .rubocop.yml is also matched with the ruby ​​version.
The .ruby-version also matches the ruby ​​version i am using.

In .rubocop.yml, rspec is set to be excluded.
However, for some reason only the request spec is warned.

I thought that parser was related from the error statement, so in the gemfile
gem'parser', '2.7.1.5'
Even if I run bundle update parser with, the error is not resolved, ...
Execute the following command after update

$bundle list | grep parser
  * parser (2.7.2.0)
  * regexp_parser (1.8.1)

Is 2.7.2.0 adopted for parser?

It doesn't matter what the trivial matter is, so please let us know.
Also, if you need other necessary data, I will upload it.
