Could not download PDF from base 64 data from web service . Why?

@anespa ur code looks perfect. but the problem here is converstion of base64 to blob.
let blobPdf = this.b64toBlob(base64pdf, ‘application/pdf’,512);

Use FetchAPI to convert the base64 to blob response. I hope this will solve ur problem.

let base64pdf = downloadPDF
 fetch('data:application/pdf;base64,' + base64pdf,{
         method: "GET"          
    }).then(res => res.blob()).then(blobPdf => {
      this.file.writeFile(this.file.externalRootDirectory, 'Ownership.pdf', blobPdf, { replace: true })
     .then(res => {
           console.log('wres', res);
         this.fileOpener.open(res.toInternalURL(), 'application/pdf').then((ores) => {
               console.log('ores', ores)
         }).catch(err => {
             console.log('open error');
         });

     }).catch(err => {
                 console.log(‘error’)
     })
