The error am getting is

and when I clicked on the link
https://reactjs.org/docs/error-decoder.html?invariant=299 the page said the full text of the error is
Target container is not a DOM element., anyone has an idea of how to fix this…?

I added a vercel.json file to see if that would solve it but it didn’t, this is the code in my vercel.json file

{
  "rewrites": [{ "source": "/((?!api).*)", "destination": "/index.html" }]
}
