I'm making a web application using reactjs, and when development is suddenly this error appears. "Error: A cross-origin error was thrown. React doesn't have access to the actual error object in development."

I still haven't tried anything. but I have undo the function that I created with ctrl + z. but this error still appears.

I don't know what code to put here, because this error suddenly appeared when I was making a login session with localstorage on reactJS – Muhammad Irva Jun 04 '19 at 10:24
