RangeError: Maximum call stack size exceeded

[JpEncausse]

What are the steps to reproduce?

I have a very simple dashboard with

• 2 LineChart Nodes : Trigger > REST Call > JS > LineChart Update (I did the trick to delete the msg.req)
• 5 Custom Node : Trigger > Template HTML > Node Call
• 1 CSS Header Node

The template look like that :

{{#room.blink}}<img class="room-blink" src="../blink/th_{{room.blink}}.jpg" />>{{/room.blink}}
<div class="room-panel room-awake-{{room.awake}}">
    <div class="room-label">{{room.label}}</div>
    {{#room.dim}}<div class="room-dim">💡️{{.}}</div>{{/room.dim}}
    {{#room.lux}}<div class="room-lux">☀️{{.}}</div>{{/room.lux}}
    {{#room.audio}}<div class="room-audio">🔊{{.}}</div>{{/room.audio}}
</div>

What happens?

I have the following error :

RangeError: Maximum call stack size exceeded
at hasBinary (/node_modules/node-red-dashboard/node_modules/socket.io-parser/dist/is-binary.js:28:19)

The Node-RED crash and restart

What do you expect to happen?

I don't understand what is happening, I assume the browser refresh a websocket connection with Node-RED And then trigger the error then crash Node-RED

Please tell us about your environment:

• [ ] Node-RED-Dashboard version: 3.1.7
• [ ] Node-RED version: 2.2.2
• [ ] node.js version: 16.15.0

It seems I find a workaround,

• I remove all Emoji but it's not the issue
• I remove all object attach to msg. that could create cycle it seems to work.

The weird thing is that payload is only a String and I assume the dashboard node do not sent the full msg. So it try to encode something that is not relevant. I continue the test.
