我们正在尝试使用聊天机器人桥（v2 代码）将对话流 api（v2）与 ui-path 编排器连接，但我们看到以下错误。
这是配置文件：default.json：
{
"server": {
"host": "127.0.0.1",
"port": 6543
},
"orchestrator": {
"hostname": "platform.uipath.com",
"tenancyName": "xxxxxxxx",
"usernameOrEmailAddress": "xxxxxxxx",
"password": "xxxxxxx"
},
"dialogflow": {
"private_key": "xxxxxx",
"projectId": "115556440368131734996"
},
}
错误：
UnhandledPromiseRejectionWarning: Error: ERR_OSSL_PEM_NO_START_LINE undefined: Getting metadata from plugin failed

请让我知道是否有任何解决方案，我们卡在这里。我们查看了 UI-Path 论坛，没有看到任何与之相关的帖子。
