Describe the bug

start from version 1.0.0-next.337 to current 1.0.0-next.343. when define a route file to catch error 404 (file named [...path].svelte) , it will catch asset urls imported in source too. This issue not happend until ver 1.0.0-next.336 .

Change log 337

i guess that the change in v*.337 regards to
Only run viteServeStaticMiddleware after server has attempted response (https://github.com/sveltejs/kit/pull/4974) will be cause. But dont know how to help fix.

Reproduction

• create new fresh svelte-kit project use npm init svelte <folder project name>
• add image into /src/lib/assets/a.jpg
• from file /src/routes/index.svelte import image to <script> block, then create <img> tag in template.
• in /src/routes create new file name [...path].svelte, define some html like a 404 catcher page.
• run npm run dev. see image url in chrome devtool will redirect to [...path].svelte page .
• rename file [...path].svelte to [path].svelte. run dev serer again, see img show correctly.
• try add file [...path].svelte again, then run build npm run buildand thennpm run preview`, the built version work ok so issue only happend with dev mode.

Severity

blocking an upgrade

[TrungRueta]

workaround to have both assets url and 404 page is change [...path].svelte to [path].svelte. because order of routes, [path].svelte has lowest priority and still match any url not catched by higher priority routes. And assets url not matched with this format because assets urls has file .ext .
