所以我正试图使用Heroku托管一个discord bot，并且我在Heroku中设置了我的配置变量和所有内容。但当我执行client.login(process.env.TOKEN)时，它会给我一个错误：
(node:14392) UnhandledPromiseRejectionWarning: Error [TOKEN_INVALID]: An invalid token was provided.

我在网上研究过，但没有找到对我有帮助的答案
使用：：点环境
require('dotenv').config()
console.log(process.env.TOKEN)
您可能会遇到多行字符串值的问题。这可能是个问题，我的证书密钥有这个问题。试着检查它是否能正确读取一行值。
您能显示.env文件中的内容吗TOKEN=""
如果它不起作用，请尝试用令牌替换"process.env.TOKEN"。如果它也不起作用则令牌是错误的。
