[BUG] Build cache not being uploaded

[wesbos]

Describe the bug

I'm not sure if this is a wrangler/cloudflare worker CI bug, or an opennextjs bug, but the build cache between builds is not persisted.

I've confirmed I have build cache enabled:

When the build starts, we see this in the Cloudflare Dashboard:

⚠ No build cache found. Please configure build caching for faster rebuilds. Read more: https://nextjs.org/docs/messages/no-cache

this page says .next/cache is supported

When the build finishes we see this error, which as far as I can tell is a specific error to cloudflare's CI?

14:01:58.955    Uploading to build output cache
14:01:59.531    Failed to upload build output to build cache. Skipping.

inspecting a build, I see the .next/cache folder is inside of .open-next/.next/cache - could that be the issue? I don't see a way to configure where the cache lives with workers.
