Sails: Running sails@beta in production mode fails

[kokujin]

I tried running sails version @beta in production mode:

...
>> Uglifying source ".tmp/public/concat/production.js" failed. 
Warning: Uglification failed.
Unexpected token: punc (}). 
Line 3807 in .tmp/public/concat/production.js
 Use --force to continue.
error: A Grunt error occurred-- please fix it, then restart Sails to continue watching       assets
