Description

While running a nuxt application on Cloudflare workers. I noticed that no cookies were being found server side.

Inside the useCookie composable that comes with nuxt there is some logic to check if the cookie has expired:

https://github.com/nuxt/nuxt/blob/41cdaf670247004eab95395910b4a59e87e38bd9/packages/nuxt/src/app/composables/cookie.ts#L46-L55

When defining a store like this:

export const useStore = defineStore(
  'main',
  () => {
    const someState = ref('hello pinia')
    return { someState }
  },
  {
    persist: piniaPluginPersistedstate.cookies({
      expires:  new Date(new Date().setFullYear(new Date().getFullYear() + 1)) 
    }),
  },
)

The date was considered to be the global context, which Cloudflare says will return 1970-01-01.

As a solution in the limitations, I have proposed to use maxAge instead of expires.

Additional Info

This is hard to reproduce on Stackblitz as this code needs to be running on a Cloudflare worker. You can set up something basic like the above and notice that the cookie will always e expired on the worker server side.
