this.props.dangerousAsPath in _documents different on SSR and SSG

[hk86]

Hello there,

my app uses SSR and SSG. I have a multilingual website therefore I set alternate link tags in the head tag at _document.js. In order to get the current path I use this.props.dangerousAsPath. From what I see it behaves different on SSR and SSG, if I deploy the app to Vercel. I'm not able to reproduce it locally, even if I run build.

i.e.: for the page /pages/article/[id].js SSG stores /article/123 in this.props.dangerousAsPath, but in case of SSR it stores /article/123?id=123. I see this behavior on the Vercel platform, not locally.

As you can see it adds a query string of the variables used in the path. Any ideas why this is the case?
