defineCachedEventHandler strips out headers

Anyone know why this is?

export default defineEventHandler(async (event) => {
 
  console.log('headers', event.node.req.headers)

export default defineEventHandler(async (event) => {
 
  console.log('headers', event.node.req.headers)

this is good ^, i get the headers, (which i need for auth, to pass on) yet changing to

defineCachedEventHandler

defineCachedEventHandler

just logs out

{}

{}
