调用已部署的lambda函数“意外的保留字”

Question

我已经部署了一个lambda函数，该函数调用另一个lambda，但是调用它会给我一个错误

{
    "errorMessage": "Unexpected reserved word",
    "errorType": "SyntaxError",
    "stackTrace": [
        "                ^^^^^",
        "",
        "SyntaxError: Unexpected reserved word",
        "createScript (vm.js:80:10)",
        "Object.runInThisContext (vm.js:139:10)",
        "Module._compile (module.js:616:28)",
        "Object.Module._extensions..js (module.js:663:10)",
        "Module.load (module.js:565:32)",
        "tryModuleLoad (module.js:505:12)",
        "Function.Module._load (module.js:497:3)",
        "Module.require (module.js:596:17)",
        "require (internal/module.js:11:18)",
        "Object.<anonymous> (/var/task/handler.js:5:12)"
    ]
}

这是我的handler.js scrapeData函数由launch_scrapers调用的，用于获取它们的许多数据页面，现在我仅使用一个小数组进行测试

"use strict"

const deployScrapers = require("./utils")
const creds = require("./creds.json");
const st = require('./scraper')

module.exports.scrapeData = async function (page_num) {
    try {
        await st.initialise()
        await st.login(creds.username, creds.password)
        const data = await st.getJsonData(page_num)
        await st.pushToDB(data)
        return {
            statusCode: 200,
            body: JSON.stringify('Hello from scrapeData'),
        };
    }
    catch (error) {
        console.log(error)        
    }
    finally {

    }
}

module.exports.launch_scrapers = async function () {
    try {
        await st.initialise()
        await st.login(creds.username, creds.password)
        // const page_array = await st.getNumOfPages() 
        const test_page_array = [20, 21, 22, 23, 24]
        test_page_array.forEach(page => {
            console.log(page)
            deployScrapers(page)
        })
    }
    catch (error) {
        console.log(error)
    }
    finally {

    }
}

，然后在我的deployScrapers.js

中

const AWS = require("aws-sdk");

module.exports = async function (pageNum) {
    try {
        const lambda = await new AWS.Lambda({
            region: "eu-west-2"
        });

        const params = await {
            FunctionName: "lambda-node-dev-scrapeData",
            InvocationType: "Event",
            LogType: "Tail",
            Payload: JSON.stringify(pageNum)
        };
        return await lambda.invoke(params, function (error, data) {
            console.log("Deployed scraper page " + pageNum)
            if (error) {
                console.error(JSON.stringify(error));
                return new Error(`Error scraping: ${JSON.stringify(error)}`);
            } else if (data) {
                console.log(data);
                return JSON.stringify(data);
            }
    }).promise()
    }
    catch (error) {
            console.log(error)
    }
    finally {

        }
    }
