Error: [route-node][buildPath] '{routeName}' is not defined

[lance-swoop]

Getting Error: [route-node][buildPath] '{routeName}' is not defined on upgrade to 8.0.0, even though my router looks like this:

<RouterProvider router={createRouter([
  { name: 'href', path: '/href' },
  { name: 'typehref', path: '/type/href' },
  { name: 'foo/href', path: '/foo/href' },
  { name: 'bar/href', path: '/bar/href' },
])}>
  ...stuff...
</RouterProvider>

What do I need to do to fix?

I had this same problem and it took me a while to get to the bottom of it because I thought the problem was with my route definition as well, but was happened for me was one of my routes was rendering a component that contained a <Link> component, and the <Link> had an invalid routeName parameter set (I had a route called "analysis.videos" but the <Link> routeName was going to "analysis.video"). Previous versions didn't seem to throw an exception but v8 does.

I have consistently 5-10% of users have met this problem. I do not know how to fix it, because all the routes are correct.
