Has anyone been succesful saving as a PDF?

I know that we are using the saveAs function, passing in a blob, but I keep having the same issue that a lot of people have. I get the popup "ERROR: Failed to load PDF Document".

I'm saving as a excel and a txt file correctly, but PDF is not happening, no matter what.

let info = new Blob(["Hello"], {type: 'application/pdf'});
FileSaver.saveAs(info, fileName + '.pdf');

This code snipped works when I I change the type to text/plain;charset-utf-8, but it doesn't work for pdf.

Has anyone had success using SaveAs a pdf.
There was a solution that didn't work for me in #176 .
