I'm working on a NextJS project right now (I'm a beginner) and got this error when I wanted to do npm run dev. I've no errors in the code, nothing. No idea where it came from ...
Thank you in advance !
Server Error
Error: Element type is invalid: expected a string (for built-in components) or a class/function (for composite components) but got: undefined. You likely forgot to export your component from the file it's defined in, or you might have mixed up default and named imports.
This error happened while generating the page. Any console logs will be displayed in the terminal window.
