Annoying Error in console

[alieldeba]

in the last module of the free react course in chapters 8, 9, and even more of the notes app, it always gets me that error in the console and it does not appear to the teacher why?

!Error: Unknown error (/node_modules/react-dom/cjs/react-dom.development.js:3994)
!The above error occurred in the <App> component: at App (exe1.bundle.js:43:44) Consider adding an error boundary to your tree to customize error handling behavior. Visit https://reactjs.org/link/error-boundaries to learn more about error boundaries.
›Error: A cross-origin error was thrown. React doesn't have access to the actual error object in development. See https://reactjs.org/link/crossorigin-error for more information. (/node_modules/react-dom/cjs/react-dom.development.js:4005)

I have the same problem.

Hello, I was encountering the same thing and could not continue the challenges. So I tried few things and for me, it helped when I deleted line 18 from App.js (console.log(JSON.stringify(notes[0].body)))
and saved.

I suspect that this is the issue with Scrimba "sandbox" way of working.

Let me know if removing line 18 helped you.

Thanks
Karol

Hello,

I was have the same problem and I solved it by: Clear LocalStorage from : (inspect>Application>LocalStorage)

Hello All! I am having this issue as well but way earlier in the course. I just started custom components and am using my own scrim so I can practice with React18. When I test my code on codesandbox it works fine but on scrimba it returns unknown errors. I tried clearing my localStorage as advised above but am still not getting anything. Other suggestions or feedback would be appreciated.

Hey All! I ended up just using codesandbox. Another benefit is that with that, you can connect it to GitHub and save your commits. This has been really useful for note-taking and tracking certain concepts. Doesn't solve everyone's issue but it has worked for me.

Do you mean openai? Do you need to import it somewhere?
