NodeBB crashing repeatedly when loading pages templates

[esiao]

Hello I have pulled the latest version and run ./nodebb upgrade and now I have this error whenever I'm navigating on my instance which make it restart and unusable.

What is happening ? Thanks in advance for the future help.

@esiao Having this as well, dropping all widgets into the Drafts part and saving seemed to temporarily fix it.

@a_5mith Yeah fixed it, kinda hard to access the widget page but I've managed to disable them.
Some weird bug to fix it seems, anyway thanks for the quick answer.

Is this on latest nodebb core and widget essentials? I am trying to reproduce it.

@psychobunny shouldn't widget essentials use the npm module templates.js instead of the one in public.

[a_5mith]

@baris All widgets show undefined instead of body. NodeBB is latest, have tried updating widget-essentials too.

Alright this is fixed now on latest widget essentials, please update.
