Error "Root"

[Lee1887]

Hello, I have a small issue.
I installed everything, but it still displays a root error.
Can someone identify the issue for me by looking at the error code?
I recently switched my navbar, called sidebar, to tailwindcss, which is a little unsatisfactory.
However, it always notifies me of the problem.

Thank you very much for the response.
I'll be visiting my neuropsychiatrist in Stuttgart.

Can you add a link to your repository/code?
It looks like const root was already used before. (You cannot declare a const twice)
