Xlsx 秘诀：使用模板时添加图片失败

它适用于空示例，但如果我上传模板，我会收到错误消息：

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/', '')

此错误发生的原因很简单，就是使用 jsreport 提供的示例代码添加图像，然后在 google 驱动器上创建空的 xlsx 文件 > 下载它 > 作为模板上传并将其包含在报告中。

看起来我没有做错任何事，但文件格式与他们预期的不同，问题将在下一个版本中修复，他们在论坛中回答：
