app_path is not available on the web

Error message

app_path is not available on the web

What it means

Sentinel from the web platform's app_path: there is no application bundle or binary path concept in the browser, so this accessor unconditionally returns this error. Any caller assuming a native install path will always fail on the web.

Solutions

1. Avoid app_path in web builds; feature-gate code that needs a native install location
2. Use a URL/origin-based identifier as the web equivalent of the app identity
3. Handle the Err to disable path-dependent features (updater, relative resources) on the web
