Hi has anyone seen this on Dashboard 2.0 template node.  
I missed the closing Curly bracket {{item.appKey} and that crashed NR and requires a stop/start?

I also tried on a simple example in the template node this does the same {{msg.payload}.  
Though missing the opening Curly bracket {msg.payload} works.

I've just tested this and Node-RED does not crash for me.

Please provide a minimal demo reproduceable flow and the following versions:

1. node-red
2. dashboard
3. node (`node -v`)

Hi Steve I've tried this on two different Nr instances and the same behaviour.  
Hit deploy flow becomes unresponsive and dashboard just shows loading.  
NR v3.1.9 & Dashboard 2 v1.7.1

Is it node red that crashes or the browser hanging?

I can confirm it locks up the browser. Node-red runtime is not affected. closing tabs or restarting browser is enough to recover.

Sadly it is all too easy to lockup the browser with silly errors in a template node, I seem to manage it regurlarly. Part of the problem is the lack of syntax checking in the template editor.

I reported an occurence the first time I saw this [Dashboard 2 Beta development - #42 by Colin](https://discourse.nodered.org/t/dashboard-2-beta-development/83550/42)
