Cordova SDK Plugin is installed, but xCode says it's not installed when executed

I am trying to embed Kakaotalk(a messenger app) Login feature into my app.

Kakao Cordova SDK Plugin was successfully installed.
Build was successful with Capacitor.
As I run the app with xCode simulator and I click the Kakaotalk login button, xCode give me a long error meesage.

Why does it complain that the Cordova SDK Plugin is not installed?

The error message:

Native: tried calling StatusBar.styleDefault, but the StatusBar plugin is not installed.
Native: tried calling Kakao Cordova SDK Plugin.login, but the Kakao Cordova SDK Plugin plugin is not installed.

However, Kakso Cordova SDK Plugin is installed!
