Convert Base 64 encoded image data to a JPEG and encoded PDF file in to the File cabinet.

NetSuite does convert Base64 image data to a JPEG file in the file cabinet automatically. I have tried different methods to decode the base 64 encoded image data. Failed to save the image data to a folder created in file cabinet.

solution: Use N/encode module, in file.create() use “file.Encoding.BASE_64” for encoding type. Instead of trying this i have ignored this encoding type. After using this method the image file successfully saved to file cabinet.

let fileObj = file.create({
    name: 'testWorld.jpg',
    fileType: fileObj1.fileType,
    contents: imageFileContent1,
    encoding: file.Encoding.BASE_64,
    folder: 757,
    isOnline: true
});
let fileId = fileObj.save();

To save base 64 encoded PDF file to file cabinet, no need to use 
"encoding: file.Encoding.BASE_64" , Netsuite directly save the file content to file cabinet.
let imageFileContent1 = fileObj1.getContents();
let fileObj = file.create({
    name: 'pdfnew.pdf',
    fileType: fileObj1.fileType,
    contents: imageFileContent1,
    folder: 757,
    isOnline: true
});
