Trailing slash on SPA route

Hey. 
I'm using Servor to serve an SPA with `create-react-app`
The problem is - whenever my SPA route ends with a slash I have 404.
  
For example, let's say I'm serving my app from `https://myapp.com`, and I have a react route `/hello-world`.
This URL works fine `https://myapp.com/hello-world`
But this one gives me 404 `https://myapp.com/hello-world/`
