Is there a way to use a

@

in a URL? in a rule?

/ # oathkeeper rules get ory:runway:ui-svelte-dev -e <http://127.0.0.1:4456>
{
	"authenticators": [
		{
			"handler": "anonymous"
		}
	],
	"authorizer": {},
	"id": "ory:runway:ui-svelte-dev",
	"match": {
		"methods": [
			"GET"
		],
		"url": "<http://ui.runway.127.0.0.1.nip.io/>\u003c{@fs/**}\u003e"
	},
	"mutators": null,
	"upstream": {
		"url": "<http://host.docker.internal:3000>"
	}
}

It seems to be loaded, but I get the following error:
