使用Node.js将数据上传到DynamoDB致命错误：接近堆限制的无效标记压缩分配失败

我在使用Visual Studio的node.js中有以下代码，该代码从mongo数据库获取数据，将其重新格式化，然后将其上传到dynamoDB：

const sync = async (event, context) => 
{
    const schoolName = "high_school";
    var school = encodeURIComponent(schoolName);
    const uri = `mongodb+srv://${username}:${password}@${host}/${school}?retryWrites=true&w=majority`;
    const db = mongoose.createConnection(uri,{ useNewUrlParser: true });
    const SchoolsModel = db.model("session_attendances", new Schema({ name: String }));
    const Schools = await SchoolsModel.find().select("_id date attendance_code session student ").lean();

    let save = function () {
        console.log("entered save function");
        var input = Schoolsjson;       
        var params = {
            TableName: "School1",
            Item:  input
        };
        docClient.put(params, function (err, data) {   
            if (err) {
                console.log("users::save::error - " + JSON.stringify(err, null, 2));                      
            } else {
                console.log("users::save::success" );                      
            }
        });
    }

    let Schoolsjson = "";
    for (const School of Schools) 
    {
        const SchoolSave = {
        PK: "STU#<" + School.student.toString() + ">",
        SK: "SESSATT#<" + School._id.toString() + ">",
        date: School.date.date,
        attendance_code: School.attendance_code,
        session: School.session,
    };
    Schoolsjson=SchoolSave;
    await save();
    }
    db.close();
    return { process: "Complete" };
};

但是，出现以下错误：

FATAL ERROR: Ineffective mark-compacts near heap limit Allocation failed - JavaScript heap out of memory

有人知道我该如何解决吗？

您可以尝试这两件事吗：
