Firefox Permissions Transform

I have the following in my package.json
"manifest": {
    "key": "$CRX_PUBLIC_KEY",
    "permissions": [
      "identity",
      "alarms",
      "notifications",
      "offscreen"
    ],
    "externally_connectable": {
      "matches": [
        "*://*.caddiedash.com/*"
      ]
    }
  }


However building with the firefox-mv3 target, I get a huge blurb of errors:
