Answer 1

感谢 Tanaike 和对代码的一些更改 - 这个问题已经解决。请参阅下面更新的代码。

  // Copy a slide from another presentation and inserts it.
  var otherPresentation = SlidesApp.openById('1Fz6YWCyLIdHfDoonz-40qRlmnNCWwROIQjXqYwmRxS8');
  var currentPresentation = SlidesApp.openById(documentId);
  var slide_v1 = otherPresentation.getSlides()[0];
  var insertionIndex = 1;
  currentPresentation.insertSlide(insertionIndex, slide_v1);

在getSlides()之后使用[0]肯定有帮助

我已删除 .duplicate() 因为它会在模板上创建重复项。
