Add resource: Allow URI scheme for Obsidian links and other app's custom protocols

What would you like to change?

Error: An Unexpected Error Occured

I get the error message when trying to Add resource with an app protocol uri instead of a web resource..

Example urls:
obsidian://open?vault=Agents&file=%2B%2F2026-08-23%20Hindsight%20Per-Profile%20Bank%20Isolation
obsidian://adv-uri?vault=Agents&filepath=%2B%2F2026-08-23%20Hindsight%20Per-Profile%20Bank%20Isolation.md

Current Docker version v2.30.1

Additional context

It's a custom-protocol deep link, not a web URL.
obsidian:// — the URI scheme Obsidian registers with the OS. Activating it doesn't load a page; the OS hands the whole string to the Obsidian desktop app.
