Answer 1

one way would be to handle it as a blob

  selectedFile(event): void {
        if (event.target.files && event.target.files.length) {
          let file = event.target.files[0];
          this.yourFormData = new FormData();
          let blob = new Blob([file], {
            type: 'application/octet-stream',
          });
          this.yourFormData.append('file', blob);
        }

  }
