⚠️ Konimage Service - Cache Write Error

✗ Error: attempt to write a readonly database
ImageMagick needs to write to Deno cache, but ProtectHome=read-only blocked it

Error from Journal

error: Uncaught (in promise) Error: attempt to write a readonly database
  const cache = await caches.open("magick_native");
                             ^
    at CacheStorage.open (ext:deno_cache/01_cache.js:46:27)
    at initialize (imagemagick_deno@0.0.31/mod.ts:15:30)

Fix Applied

Removed ProtectHome and added cache to writable paths:

ReadWritePaths=/konnectvol /home/bb/.cache

Run These Commands

sudo cp /tmp/konimage.service /etc/systemd/system/konimage.service
sudo systemctl daemon-reload
sudo systemctl restart konimage
sudo systemctl status konimage

Why: The ImageMagick WASM library caches its binary in Deno's cache directory (~/.cache/deno). Systemd's ProtectHome blocked writes to home directories.
