Prefetcher.js throws Uncaught TypeError: Cannot read property ‘map’ of undefined.
/layer0/cache-manifest.js also returns 404
I’m not sure if this issue can be related to code changes. Please take a look and advice what can be the reason of it?
Can you provide your router configuration? This route (/__layer0__/cache-manifest.js) is a built-in route that is automatically added unless an option is provided to explicitly exclude it.
