Typeerror: Meta. relativePath. startsWith Is Not a Function

I just solved this same problem. The answer was here.

This is what I had that was causing the error.

    <Routes>
      <Route exact path={["/", "/user"]} element={Home} />
      <Route exact path="/add" element={AddUser} />
    </Routes>

And this is the fix that worked

    <Routes>
      <Route exact path="/" element={<Home />} />
      <Route exact path="/add" element={<AddUser />} />
    </Routes>

This error just showed up to me and it seems there are no real solutions for this problem since I made the research with no results.

I used to have my code like this, like having several routes in an array inside the path prop.

<Route exact path={['search', '/images', '/news', '/videos']} element={<Results />} />

Once I was aware there were no solutions on internet I just split every route in a single line each.

    <Route exact path='/search' element={<Results />} />
    <Route exact path='/images' element={<Results />} />
    <Route exact path='/news' element={<Results />} />
    <Route exact path='/videos' element={<Results />} />

This might not be a good solution for this but it's an option if you want to keep with your work.
