What does your your assets folder look like in your custom sprinkle? (I’m assuming you are creating a sprinkle.)
I’m using font-awesome in my own sprinkle and you can see the structure of mine in this attached image …
The vendor subfolder shown is populated by declaring the following in the sprinkle’s bower.json file (not the one found in the font-awesome folder) …
“dependencies”: {
“moment”: “^2.17”,
“chart.js”: “>= 2.7.2”,
“font-awesome”: “^4.7”
},
You should not need to make any literal asset references for font-awesome in your twig file; can’t tell from your error screen if that might be the case. (If you are doing that, simply remove the explicit reference and try your page again.)
