the red elements give an error when I insert one and try to save, the green ones don’t give an error.

save function

async save(): Promise<void> {
    const xfdf = await this.annotManager.exportAnnotations();
    const fileData = await this.docViewer.getDocument().getFileData({});
    const blob = new Blob([fileData], {type: 'application/pdf'});
    this.instance.openElements(['loadingModal']);
    return this.appService.saveAnnotation(this.imagem, xfdf).subscribe(() => {
      this.instance.closeElements(['loadingModal']);
      Swal.fire('Anotação Salva!', '', 'success').then((result) => {
        if (result.isConfirmed) {
          window.parent.postMessage('CloseIframe', '*');
          // console.log('Event: CloseIframe');
        }
      });
    });
  }
