After updated magento from 2.1 to 2.3 I've got a require js error in console:
Uncaught Error: Script error for: ModuleName
I made an investigation and find out that
require.js core file in the function
req.load is trying to create node
document.createElement('script') and then checks if this node has
attachEvent property. In my case it's script node. And there is no
attachEvent property. By this reason I've got an error.
Can somebody explain why it happens? Everything was good before and code seems was the same.
