setMaxAge('permanent') and equivalent does not create cache in red

[mathieuCatapulpe]

Hello, I've been using your module and it's been a live saver so far but I noticed an issue with setMaxAge()

Setting no TTL or using 'permanent' or -1 does not create an entry in redis

useRouteCache((helper) => {
  helper.setMaxAge('permanent').setCacheable() // or setMaxAge(-1) -> does not work
})

useRouteCache((helper) => {
  helper.setMaxAge('midnight').setCacheable() // works
})

I also tried to add a tag but it didn't change anything
