Where are you rendering your modal element? It should not the 'root'.
I see, the component with id modal ... I use typescript, it keeps giving the same error message :(
1) You can place the document.getElementById ('root') in a variable and add a null check. For example:
document.getElementById ('root')
const portalDiv = document.getElementById('root')!
2) Pass the portalDiv as the second parameter AFTER the </> closing fragment
portalDiv
</>
