使用 ibm watson 在聊天机器人中发送获取请求时如何解决错误?

How to solve an error while sending a get request in chatbot using ibm watson?

当我向 postman 发送 get 请求时,会话 ID 没有生成,而是进入 catch 块并显示发生错误,请帮我解决这个问题

const authenticator = new IamAuthenticator({
    apikey: process.env.WA_ASSISTANT_APIKEY,
});

const assistant = new AssistantV2({
    version: "2019-02-28",
    authenticator: authenticator,
    url: process.env.WA_ASSISTANT_APIKEY,
});

router.get("/session", async (req, res) => {
    //if successfull
    try{
        const session = await assistant.createSession({
            assistantId: process.env.WA_ASSISTANT_ID,
        });
        res.json(session["result"]);
    //error
    }catch(err){
        res.send("An Error occured while processiong your request!");
        console.log(err);
    }
})

This is the code Error

该错误表明您的应用正在尝试连接到本地主机上的 Watson Assistant。我怀疑错误是由于你的行 -

url: process.env.WA_ASSISTANT_APIKEY

APIKey 不太可能是 url。
