I have a question, I don't know how to implement it.
[lang]/page/[id].astro
Expect:

1. url: /en/page/10
2. url: /page/10
   I don't know how to achieve it

About another question
Use output: "hybrid"
The route will prioritize matching SSG before matching SSR.
Can I set it to match SSR first and then match SSG, because in actual website visits, I need a dynamic route. If the SSR application crashes, I can use SSG

I am looking into this and can see that we aren't handling 404 pages properly in hybrid mode. Working on a fix.

• Trailing slash behavior can be configured with the trailingSlash option
• Please open new issues for other bugs and visit our Discord for support questions.

TrailingSlash can only be used in development. In output: "hybrid" and SSG mode, it will automatically add at the end /
