Seems that you need to initialise your `sidebar` variable outside, so it can be accessed from the scope where you call `destroy()`. 

I have the same issue, when I use second argument as name it downloads an empty file.

Here is the solution, I didn't notice it in the documentation: https://github.com/rndme/download#image-via-ajax-for-custom-filename---live-demo

Thanks, `allowedContent: true` made it work on page load
