"org.apache.commons.mail.EmailException: Invalid message supplied" 使用 ACS 公共电子邮件服务发送电子邮件通知时

Question

我正在尝试在工作流程中使用 ACS 公共电子邮件服务发送电子邮件通知，但出现错误 -

*ERROR* [JobHandler: /var/workflow/instances/server0/2020-04-17_3/workflow_59:/content/path/to/page] com.adobe.acs.commons.email.impl.EmailServiceImpl Error sending email to [ user@mail.com ]

我关注了https://adobe-consulting-services.github.io/acs-aem-commons/features/e-mail/email-api/index.html

附加 html 我在我的模板中使用过（我也尝试过使用普通文本的 .txt 文件）-

<html>
   <head></head>
   <body>
      -----------------------------------------<br/>
      Time :  ${time} <br/>
      Step : Approve Content <br/>
      Approver : userName <br/>
      Workflow :  wftitle<br/>
      -----------------------------------------<br/><br/>
      wftitle  workflow has been assigned to you. Please review the content: <a href=' url'>                            payloadTitle </a><br/><br/>----------------------------------------<br/>
      View the overview in your  <a href='test'>AEM Inbox</a><br/>

</html>

请让我知道我在这里遗漏了什么。

提前致谢！

您似乎遗漏了电子邮件 headers：_ From_，主题后跟一个空行。还请确保模板的文件以“.html”结尾，如文档中所述。请务必仔细阅读您链接的文档
