Describe the Bug

I had export function getStaticPaths() returning [{ year, month, slug }, ...] for a blog and got hit by this error:

 error   [getStaticPath] route pattern matched, but no matching static path found. (/blog/2014/04/asincron-a-y-el-eventloop/)

After some navigating astro's code I found the issue comes from findPathItemByKey() not being able to find a page with such params so I added this line to astro's code:

   if (matchedStaticPath) {
     return matchedStaticPath;
   }

+ debug('test', Array.from(staticPaths.keyed.keys()))
   debug("findPathItemByKey", `Unexpected cache miss looking for ${paramsKey}`);

and a logger in my config file

globalThis._astroGlobalDebug = (...args) => console.log(...args);

And got this printed out:

test [
  '{"month":"04","slug":"asincron-a-y-el-eventloop","year":2014}',
  ...
]
findPathItemByKey Unexpected cache miss looking for {"month":"04","slug":"asincron-a-y-el-eventloop","year":"2014"}

Took me a while to find out the only difference is that year is a number in the cache while it's a string in the key we're looking for it's a string.

IMPORTANT: this is only visible with astro build
