Getting error: TypeError: Cannot read property 'setEncoding' of undefined

Code is:

Pdf=require("pdf-text-extract");
SourcePath="Path/To/File.pdf";
Pdf(SourcePath, function(Err, Pages){  //< - error at this line.
	if(Err){
		console.dir(Err);
	}else{
		console.dir(Pages);
	}
});

PDFs are bank statements with a mix of text and graphics. Didn't find any documentation online based on the error. Looking for clues.
