谷歌云功能-SendGrid-400错误请求

Question

我正在尝试使用谷歌云功能中的SendGrid发送电子邮件。我在Firebase环境变量中有我的密钥，所以这是存在的。

const sgMail = require('@sendgrid/mail');
sgMail.setApiKey(SENDGRID_API_KEY);

这是我的GCF.ts代码：

代码

const msg = {
to: to,
from: from,
subject: 'Email Subject',
content: [{
type: "text/html",
value: body
}]
};
await sgMail.send(msg)
.then(r => {
console.log(r);
});

当我触发该功能并检查日志时，这就是我得到的错误：

错误

body: { errors: [Object] } } }

有人熟悉这个错误吗？它提到了CORS，但这毫无意义，因为它是一个云功能，而不是浏览器。SendGrid API并不是很好，它主要介绍了字段名称，没有提供任何示例。感谢您提供的任何帮助！

编辑

只是为了更新这个问题，在我发给自己的前端响应中，我发现了一个与GCF日志中的console.log(error)不同的错误：

"Email failed: Bad Request (400)
The from object must be provided for every email send. 
It is an object that requires the email parameter, 
but may also contain a name 
parameter.  e.g. {"email" : "[e-mail]"}  or 
{"email" : "[e-mail]", "name" : "Example Recipient"}.
from.email

第2版：解决方案

我的发件人电子邮件来源来自Firestore中的一个文档，我试图获取一个不存在的字段，因为我查询了错误的文档，因此from是undefined。更正了它，并根据下面的建议/答案删除了msg对象中的"内容"，一切都很好。

根据文档。。。msg有错误的元素：

const sg = require('@sendgrid/mail');
sg.setApiKey(process.env.SENDGRID_API_KEY);
const msg = {
to: '[e-mail]',
from: '[e-mail]',
subject: 'Sending with SendGrid is Fun',
text: 'and easy to do anywhere, even with Node.js',
html: '<strong>and easy to do anywhere, even with Node.js</strong>',
};
sg.send(msg).then(() => {
/* assume success */
})
.catch(error => {
/* log friendly error */
console.error(error.toString());
/* extract error message */
const {message, code, response} = error;
/* extract response message */
const {headers, body} = response;
});
