Xdebug not running on Sail

Hi, I can't get xdebug working on Sail. I've followed the steps in the Laravel Sail docs and also tried this article https://iwasherefirst2.medium.com/how-to-set-up-xdebug-with-laravel-sail-a-complete-guide-98d6498b382a

My launch.json is

{
	"version": "0.2.0",
	"configurations": [
		{
			"name": "Listen for Xdebug (Sail)",
			"type": "php",
			"request": "launch",
			"port": 9003,
			"pathMappings": {
				"/var/www/html": "${workspaceFolder}"
			},
			"log": true,
			"hostname": "localhost"
		},
		{
			"name": "Launch currently open script",
			"type": "php",
			"request": "launch",
			"program": "${file}",
			"cwd": "${fileDirname}",
			"port": 0,
			"runtimeArgs": [
				"-dxdebug.start_with_request=yes"
			],
			"env": {
				"XDEBUG_MODE": "debug,develop",
				"XDEBUG_CONFIG": "client_port=${port}"
			}
		}
	]
}

I'm running Laravel 12 and VSCode on Linux. I have other projects that run non-Sail docker setups with xdebug working, but for some reason I'm doing something wrong with Sail.

Am I missing anything? Thanks.
