Blank PDF file is generated when called first time

[Ramya-Kakarla]

Below is the code snippet to generate and save the pdf directly into the file system.
Getting the html as shown below.
` var htmlContent = document.getElementById('page-content');
var pdfhtml =''+
'
'+ htmlContent.innerHTML + '';

var fileName = file + ".pdf";
var options = {
documentSize: 'A4',
type: 'base64'
};
pdf.fromData(pdfhtml, options)
.then(function (base64) {
var contentType = "application/pdf";
var folderpath = cordova.file.externalRootDirectory + "Download/";
savebase64AsPDF(folderpath, fileName, base64, contentType);
})
.catch(function (e) {
console.log(e)
});`

It's generating a blank PDF when called the first time. Works fine in the subsequent calls.
No errors are shown when the blank file is generated.
