event.waitUntil is not available in defineCachedEventHandler

[DTesch-Level-R]

Environment

nitro v2.10.4

Reproduction

export default defineCachedEventHandler(async (event) => {
event.waitUntil(asyncTask()); // ❌ Throws error: "event.waitUntil is not a function"

return { success: true };
}, { maxAge: 60 });

export default defineEventHandler(async (event) => {
event.waitUntil(new Promise((resolve) => setTimeout(resolve, 3000))); // ✅ Works as expected
});

Describe the bug

When using defineEventHandler(), calling event.waitUntil() works as expected and allows asynchronous tasks to continue running after the response has been sent. However, inside defineCachedEventHandler(), event.waitUntil() is undefined, causing an error when attempting to use it.

Is this expected behaviour?
If event.waitUntil() is unavailable, how can I ensure my Cloudflare Worker does not terminate my defineCachedEventHandler() before an asynchronous function completes?
