An error message when I inspect my shopify website

Hello! So I get this error message when I got to inspect my website. Anyone know where this came from? Or possibly from what app I downloaded that could cause this issue. 

script2.js?shop=3brothersliquor.myshopify.com:1 Uncaught TypeError: Cannot read property 'getAttribute' of null
