When loading my page and running JSZip I'm getting this error:

Failed to load resource: the server responded with a status of 404 (Not Found) http://localhost:8000/Libs/rawinflate.min.js.map

and

Failed to load resource: the server responded with a status of 404 (Not Found) http://localhost:8000/Libs/rawdeflate.min.js.map

I can't find the file 'rawinflate.min.js.map' or 'rawdeflate.min.js.map' anywhere in the 'Stuk-jszip-v2.0.0-2-g7718693' download file. Is anyone else getting this error? Btw I'm running a nodejs server for local development, but I've uploaded it to my site and get the same error (its hosted by lunarpages if that helps). Also the error is appearing over and over again when I open the console.

Thanks for any help!
