-# sv
+**This repo reproduces the error in the current SvelteKit version.**
 
-Everything you need to build a Svelte project, powered by [`sv`](https://github.com/sveltejs/cli).
+App in the repo has such routing
 
-## Creating a project
-
-If you're seeing this, you've probably already done this step. Congrats!
-
-```bash
-# create a new project in the current directory
-npx sv create
-
-# create a new project in my-app
-npx sv create my-app
-```
-
-## Developing
-
-Once you've created a project and installed dependencies with `npm install` (or `pnpm install` or `yarn`), start a development server:
-
-```bash
-npm run dev
-
-# or start the server and open the app in a new browser tab
-npm run dev -- --open
 ```
-
-## Building
-
-To create a production version of your app:
-
-```bash
-npm run build
+(app)
+-- [id=bigint]
+---- +page.svelte
+-- +error.svelte
 ```
 
-You can preview the production build with `npm run preview`.
-
-> To deploy your app, you may need to install an [adapter](https://svelte.dev/docs/kit/adapters) for your target environment.
-# svelte-mathing-error
+When you open the page with the parameter which is not bigint, you should see the +error page.
+But, instead, you see the default SvelteKit error page.
+Excepted behavior: +error page should be shown.
