Azure 逻辑应用程序 - 在新电子邮件上 - 附件有空字节

Question

为什么附件没有被正确读取？

---

尝试使用快速启动模板将电子邮件中的附件保存到 SharePoint 文件夹。

工作流程：

• 收到新邮件（成功）
• 对于每个容器（传入Attachments）
  • 创建文件（失败）

在新邮件上 > 输出 > 附件

在新邮件上显示成功，但附件内容设置为空("ContentBytes": null):

  }
]

对于每个容器 > 创建文件

因以下原因失败：

InvalidTemplate. Unable to process template language expressions in action 'Create_file' inputs at line '1' and column '11': 'The template language function 'base64ToBinary' expects its parameter to be a string. The provided value is of type 'Null'. Please see https://aka.ms/logicexpressions#base64ToBinary for usage details.'.

触发器上有一个 "include attachments " 选项可以选择包含字节。确保它已打开并且它应该可以工作。
