I am always getting null for doc when I pass a file into createDocument. i dont see any errors in the console on createDocument

Not sure how to identify what the issues is
Following Get-file-data-without-viewer | Apryse Documentation

Code is

            Core.setWorkerPath('src/wv-resources/lib/core');
          
             Core.createDocument(file, { l: 'demo ,  extension : 'docx'})

.then(doc => {

doc.getFileData().then(data => {



      const arr = new Uint8Array(data);
      const blob = new Blob([arr], { type: 'application/pdf' });

});

})
.catch(err => { })

Please provide a link to a minimal sample where the issue is reproducible:
