Facing same problem

[athomann]

I believe this is because of React 18 changing typing for children

[tanzeelrana]

same issue, anyone found out whats going on ?

[foscjos2]

@tanzeelrana as mentioned above, react 18 changed the typing for children. AFAIK the children prop used to be included by default, now its not. You need to either add it manually to your props interface (something like "children?: React.ReactNode | undefined;") OR wrap your props in React.PropsWithChildren (React.PropsWithChildren).

What that likely means in the scope of this library, is that until the maintainer updates the props for his interfaces to include the children prop, this library is incompatible with react 18.

For now, you can use patch-package to do the change locally:

Example diff: (v6.7.0)

diff --git a/node_modules/connected-react-router/index.d.ts b/node_modules/connected-react-router/index.d.ts
index c56beb1..5d59f58 100644

The TSC error went away for me :)
