Capacitor writeFile - Saving pdf file is in invalid format

@wekas wrote:

I am generating a pdf using pdfMake and writing it to an android device so that I can open it.
I am using Capacitor and the file system command does not appear to take a blob (this worked in cordova) so I am sending it a base64.
It seems to write ok but when I open the pdf it says the format is invalid.

Note: The cordova file plugin does not work with Capacitor (Cordova plugins not working with Capacitor) so it seems I am stuck with Capacitor file system commands.

Can I write to blob in capacitor or is there a problem with my code??

Help please, I have spend days on this!

   this.pdfObj = pdfMake.createPdf(docDefinition);

    if (this.plt.is('cordova')) {
      this.pdfObj.getBase64((data) => {
        this.pdfBase64 = data;
        console.log(this.pdfBase64);
      });
    }
  }

  downloadPdf() {
    const { Filesystem } = Plugins;

    if (this.plt.is('cordova')) {
      console.log('3');
        // Save the PDF to the data Directory of our App
        const fileName = 'defectreport.pdf';
        try {
          Filesystem.writeFile({
            path: fileName,
            data: this.pdfBase64,
            directory: FilesystemDirectory.Data,
            encoding: FilesystemEncoding.UTF8
          }).then((writeFileResult) => {
            console.log('File Written');
            Filesystem.getUri({
                directory: FilesystemDirectory.Data,
                path: fileName
            }).then((getUriResult) => {
                console.log(getUriResult);
                const path = getUriResult.uri;
                this.fileOpener.open(path, 'application/pdf')
                .then(() => console.log('File is opened'))
                .catch(error => console.log('Error openening file', error));
            }, (error) => {
                console.log(error);
            });
          });
          console.log('writeFile complete');
        } catch (error) {
          console.error('Unable to write file', error);
        }
