AutoHost isn't working

[TangentFoxy]

After following the instructions at https://polymer.pb4.eu/latest/user/resource-pack-hosting/ my server does not use the resource pack. I also tried making it required and it still doesn't work. Everything works if I manually copy the generated resource pack, it's just automatically using it that isn't functioning. I am running server and client on the same machine to make sure it works before setting up anything more permanent, using localhost to connect.

What am I missing?

Version 1.20.4 of Minecraft, Polymer 0.7.8.

Hmm thats weird. Make sure that you enabled it correctly in the config! Ideally by also editing it before starting the server. If you don't see any logs related to resource packs on the server (at the end of loading), then it isn't enabled

Which config? What does correctly mean? According to instructions, all that is needed is to change a value in config/polymer/auto-host.json. What logs should I be seeing? This is what appears:

I removed almost everything I was trying to use in case it was one of them breaking things before trying again, and it still doesn't work.

Hmm thats weird, it should work then. Maybe you didn't accept it on client? Through check if there is ending message for resource pack generation as logs you provided only have starting one

The client acts as if the server does not have a resource pack.

Through check if there is ending message for resource pack generation as logs you provided only have starting one

That is the entire output. Nothing else happens except for logs generated by in-game actions.
