Player kicked with error for certain filter

I tried using this to filter skilltree messages, this in particular (see screenshot).

Here's the rule:

    {
      "Text to match": "You received a refund ",
      "Is RegEx (Advanced)": false,
      "Show as notification": true,
      "Keep in chat": false,
      "Game Tip Settings": {
        "Show as Game Tip": false,
        "Game Tip color (true = blue - false = red)": true
      },
      "Formatting": {
        "Color setting": {
          "Use custom color": false,
          "Custom color": null
        },
        "Regex formatting (Advanced)": {
          "Enabled": false,
          "Pattern": null,
          "Replacement": null
        }
      }
    }

Console error:

Actually this seems unrelated to that, as i reverted to my original config and still get this error. I believe its due to the changes in 1.4.0 for the new UI elements since the error is in AddUI

Here's the error on client side:

RPC Error in AddUI: Object reference not set to an instance of an object.

Working normally on my end, not sure what could be causing that .. 

With my config it worked for you?

It's the same problem.

I've reverted to the previous version for now.

Ok so got a couple of questions to try to replicate:

1. What's the server version? is it up to date?
2. Is it all players or some players?
3. Does some notifications show up then suddenly this happens or right from first sent it kicks the player?

@SLATE @K9N_Twitch

'Carbon' v2.0.170.0

Protocol	2602.272.1
Build Date: 10/04/2025 09:45:21
Unity Version: 2022.3.41f1
Changeset: 133099
Branch: release

2. I'm not sure, I reverted it after it occurred to me twice on my server when no one else was connected.

3. I didn't notice any notifications come up before i was kicked

I just tested with me and another player. first notification that came through kicked us both.

Oh carbon i see forgot to test there, wonder if it was carbon for K9N too.

YES!!

ああ、カーボンですね、そこでテストするのを忘れていました。K9N もカーボンだったのかな。

Gotcha thanks for the info, will revert the version now and check with Carbon why that's happening.

let me know if you need any testing, i should be around in about 8-10 hours

Found and reported bug to Carbon, added the following to v1.4.1 which fixes it till Carbon fixes it from their side too.

#if CARBON
	CuiHelper.AddUi(player, CuiHelper.ToJson(cont).Replace("\"verticalFit\":2", "\"verticalFit\":\"PreferredSize\""));
#else
	CuiHelper.AddUi(player, cont);
#endif

Thank  you

all fixed. thanks!

Changed Fixed In to 1.4.1
