* @param backgroundColor Background color. Default: '#fee'

* @param err2 Is the second param is a string, you can put the original Error in here

* @returns A div element with the err string

*

* This will return a DOM element you can put in the UI as a notice for the user

* Meanwhile the stack is dumped to the console for the developer, so you actually know
