The following setup works for me. Hope this one can helps you.

let form = new w2form({
  name: 'testForm',
  fields: [
    { field: 'name', type: 'text', html: { label: 'Name' } },
    { field: 'inputFile', type: 'file', html: { label: 'Upload File' } }
  ]
});

let data = {
    name: 'Test Name',
    inputFile: [
       { 
          'name': 'test.jpg',
          'type': 'image/jpeg',
          'content': {btob data},
          'size': 19303
       }
   ]
};
form.record = data;
