Xlsx食谱：使用模板时添加图像失败

它适用于空示例，但是如果我上传模板，则会出现错误：

Error while executing templating engine. Cannot read property 'r:id' of undefined. Error on line 270:98.

  268 |     var drawingFullName
  269 |     if (this.ctx.root.$xlsxTemplate['xl/worksheets/' + sheetFullName].worksheet.drawing) {
> 270 |       var rid = this.ctx.root.$xlsxTemplate['xl/worksheets/' + sheetFullName].worksheet.drawing.$['r:id']
      |                                                                                                  ^
  271 |       this.ctx.root.$xlsxTemplate['xl/worksheets/_rels/' + sheetFullName + '.rels'].Relationships.Relationship.forEach(function (r) {
  272 |         if (r.$.Id === rid) {
  273 |           drawingFullName = r.$.Target.replace('../drawings/', '')

仅通过获取jsreport提供的示例代码来添加图像，然后在Google驱动器上创建空的xlsx文件，然后下载并上传它作为模板并将其包含在报告中，就会发生此错误

看起来我没做错任何事，但是文件格式与他们期望的不同，该问题将在下一个版本中得到解决，因为他们在论坛上回答了这个问题：
