Heroku给出BABEL_PARSE_ERROR，等待在部署后得到意外保留字

Question

我正在开发一个Facebook信使聊天机器人。在上次部署到Heroku之后，我收到了Heroku控制台的BABEL_PARSE_ERROR，并说wait是意外的保留字。我的依赖项如下。。我使用的是node最新版本(16.14.0(

"dependencies": {
"@babel/core": "^7.17.2",
"@babel/node": "^7.16.8",
"@babel/preset-env": "^7.16.11",
"dotenv": "^14.2.0",
"ejs": "^3.1.6",
"express": "^4.17.2",
"nodemon": "^2.0.15",
"request": "^2.88.2"
}

我在访问Heroku控制台时出错。。。

以下是我的代码，指的是。。。

const sendWelcomeNewUser = (sender_psid, response) => {
return new Promise((resolve, reject) => {
try {
let username = await homepageService.getFacebookUserName(sender_psid);
let response = {
text: `Hey! ${username}. Pick your language:`,
quick_replies: [
{
content_type: "text",
title: "සිංහල",
payload: "SINHALA",
},
{
content_type: "text",
title: "English",
payload: "ENGLISH",
},
],
};
await sendMessage(sender_psid, response);
} catch (e) {}
});
};

请帮助

Answer 1

问题解决了！我还没有将异步包含到该函数中。根据该函数应如下。。

const sendWelcomeNewUser = (sender_psid, response) => {
return new Promise( async (resolve, reject) => {
try {
let username = await homepageService.getFacebookUserName(sender_psid);
let response = {
text: `Hey! ${username}. Pick your language:`,
quick_replies: [
{
content_type: "text",
title: "සිංහල",
payload: "SINHALA",
},
{
content_type: "text",
title: "English",
payload: "ENGLISH",
},
],
};
await sendMessage(sender_psid, response);
} catch (e) {}
});
};

这解决了我的问题。
