Question

为什么附件无法正确读取？

---

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:

• 收到新电子邮件(成功)
• 对于每个容器(传入附件)
  • 创建文件(失败)

在新电子邮件上 > 输出 > 附件

在新邮件上似乎成功，但附件内容设置为 null ("ContentBytes": null):

[
  {
    "Id": "AAMkADlhMDBiODNiLWFmOTEtNGZjOS1hMjYxLTY1OTU3MDk4YzZjNABGAAAAAACijX5OkcblRIVMFzOsYgiSBwBFaJ_hCA08Tb5SmdY6ZqCxAAAAADB8AABFaJ_hCA08Tb5SmdY6ZqCxAACD6w2UAAABEgAQAOCw7xb1bG9LstW5SRafEOE=",

    "ContentBytes": null
  },

  }
]

对于每个容器>创建文件

失败并出现以下情况:

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“包含附件”选项，可以选择包含字节。确保它已打开并且应该可以工作。
