Error trying to setup security/xray-core client

[tembun]

I have a VPS on which I set up an Xray + VLESS + Reality VPN using 3x-ui panel. Now I can use that VPN on my Android phone using Hiddify app. I scanned the QR code generated by the GUI panel interface and it made a proper client config that can be used to connect to the server from phone.

Now, I'd like to also be able to connect to this VPN from my FreeBSD machine. There's a port security/xray-core, which seems to be the client. I copied a client JSON config from Hiddify app:

{
    "outbounds": [
        {
            "type": "vless",
            "tag": "vless-temcbun",
            "server": "<my-VPS-IP>",
            "server_port": 21193,
            "uuid": "<my-client-uuid>",
            "tls": {
                "enabled": true,
                "server_name": "dl.google.com",
                "utls": {
                    "enabled": true,
                    "fingerprint": "chrome"
                },
                "reality": {
                    "enabled": true,
                    "public_key": "<my-client-public-key>",
                    "short_id": "<short-id>"
                }
            },
            "transport": {
                "type": "xhttp",
                "mode": "auto",
                "path": "/",
                "xPaddingBytes": "100-1000"
            },
            "packet_encoding": "xudp"
        }
    ]
}

and I wrote it into /usr/local/etc/xray-core/06_outbounds.json.

Now I want to try the whole thing out and start it, but I got an error (as root):

The error itself:

infra/conf: failed to build outbound config with tag vless-temcbun
> infra/conf: failed to load outbound detour config for protocol
> infra/conf: unknown config id:

doesn't help me much (I have no idea how to fix it)

I'm very-very new to network related things (don't have much experience), so I'd like to ask for some help to troubleshoot and solve this issue.
I'd appreciate any help!

There's a port security/xray-core, which seems to be the client.

No, similar to security/openvpn it can be configured for all sorts of tasks, as client, server or anything in between.

Never used security/xray-core, but looking at the default configuration files it seems you're probably missing some other parts of the configuration, it's not only 06_outbounds.json that needs to be configured. The other files are mostly empty.
