Invalid Cache Mounts

Running into a wall with trying to run a fairly straightforward Go HTTP server. Using the newer features in the stdlib for net/http on Go 1.22. So after multiple build failures before learning Nixpacks doesn't support that version yet, I'm having to go the Dockerfile route. Using the generated Dockerfile, which uses caches for the build steps, I added the id=<service_id>-<path>,target=<path> where needed, but I still am running into the error Invalid cache mounts. I've attached a screenshot of the relevant Dockerfile parts and the error in the build logs.

Solution:

you can only use cache type mounts, not bind mounts
