### Describe the bug We're hosting sveltekit with SSR in a Docker container that's hosted in azure. We have datadog to track errors and we tend to see about 3 to 30 of these 404's a day on our small-medium site. We played around with azure cdn cache, but when we enabled this, the errors really came to show, so we disabled the azure cache. When doing so, it went back to it's normal occurance. This issue is the same as this question posted a while ago; https://github.com/sveltejs/kit/discussions/7057 Example error for a 404 asset: ``` Error: Not found: /_app/immutable/assets/_layout-c5c8ebf1.css at resolve (file:///app/server/index.js:2276:18) at resolve (file:///app/server/index.js:2163:34) at Object.handle (file:///app/server/chunks/hooks.server.js:379:10) at runMicrotasks (<anonymous>) at runNextTicks (node:internal/process/task_queues:61:5) at processImmediate (node:internal/timers:437:9) at async respond (file:///app/server/index.js:2161:22) at async Array.ssr (file:///app/handler-393b2283.js:1102:3) ``` What might be the cause of this type of error, Is it just something that happenes when document is out of sync with assets, or is it something we can do to keep this from happening?  ### Reproduction - ### Logs _No response_ ### System Info ```Shell System: OS: macOS 12.5.1 CPU: (8) arm64 Apple M1 Memory:
