When compiling to production I receive an error

[brooksdubois]

19:58:41 - error: Optimizing of public/app.js failed. L10776:21 SyntaxError: Unexpected token: operator (>)

Everything works normally, just build fails when compiling to production.

I am using coffescript +ejs + jquery. Also, using uglify to minimize for production.

here is my config:
{
"dependencies": {
"ejs-brunch": "^1.0.2",
"jquery": "^3.3.1"
},
"devDependencies": {
"auto-reload-brunch": "^2.7.1",
"brunch": "^2",
"clean-css-brunch": "^2.10.0",
"coffee-script-brunch": "^2.10.2",
"stylus-brunch": "^2.10.0",
"uglify-js-brunch": "^2.10.0"
}
}

@brooksdubois Could you try this again? I've just merged a PR that replaces arrow functions to make it compatible with ES5, maybe that was the problem.

1. started the watch server,
2. npm install --save ejs-brunch
   --update appears normal
3. kill the watch server
4. brunch build --production
   --I set the logging on
   --I hope its useful. looks like its a problem with ugliy. If I take the ejs files out everything works normally. could be on their end. if so, sorry to bother you

Output:
