SuiteScript - Map/Reduce - 没有上下文值从reduce 阶段传递到summary 阶段

Question

我是新手，目前正在学习 SuiteScript。我无法理解为什么没有上下文值从reduce 函数传递到summary 函数。日志结果显示上下文值，除了： {"type":"mapreduce.Summary","dateCreated":"2023-08-29T17:02:27.014Z","seconds":9,"usage": 190,"concurrency":5,"yields":0}"，这导致发生错误。但是，Reduce Context 日志按预期显示值。

有人愿意帮助我了解我做错了什么或我应该做什么吗？预先感谢您的协助；我真的很感激。

我的代码示例如下，我期望从reduce阶段获取'fileList'上下文到summary阶段。

代码示例如下：

function reduce(context) {
    try {

        var transactions = JSON.parse(context.values[0]); // Parse the file contents loaded from getInputData

        log.debug('Reduce Context', transactions); // This logs the values as expected

        if (transactions && transactions.length > 0) {
            // Iterate through file transactions array
            transactions.forEach(function (transaction) {
                /** .... performing other tasks with transaction object
                .........to create and save journal
                */
                // Build the file list array and write context that needs to be moved
                context.write({
                    key: "fileList",
                    value: {
                        fieldId: transaction.fileId,
                        duplicate: transaction.duplicate,
                        failed: transaction.failed
                    }
                });
            });
        }
    } catch (e) {
        log.error('Reduce Error', 'Error in Reduce function => ' + e.name + ' : ' + e.message);
    }
}

function summarize(context) {
    try {

        log.debug('Summarized Context', context); // The log results show nothing for the context value

        fileList = JSON.parse(context.values[0]); // Parse the context values loaded from reduce stage
        if (fileList && fileList.length > 0) {
            //Iterate through the file list array and move each file to the relevant folder
            fileList.forEach(function (file) {
                var fileObj = file.load({
                    id: file.fileID
                });
                if (file.duplicate === "Y") {
                    fileObj.folder = DUPLICATE_FILE_FOLDER_ID; // Move the file from Pending Folder to Duplicate Folder
                } else if (file.failed === "Y") {
                    fileObj.folder = FAILED_FILE_FOLDER_ID; // Move the file from Pending Folder to Failed Folder
                } else {
                    fileObj.folder = PROCESSED_FILE_FOLDER_ID; // Move the file from Pending folder to Processed Folder
                }

                fileObj.save();
            });
        }
    } catch (err) {
        log.audit('File Moving Error', err.name + ' : ' + err.message);
    }
}

summarize 使用不同的上下文。没有值成员。

对于您所呈现的内容，您想要类似的内容：

const fileRefs = [];
ctx.output.iterator().each((key, value)=>{
   if(key == 'fileList'){
      var fileRef = JSON.parse(value);
      fileRefs.push(fileRef);
      return true;
   }
});
fileRefs.
   filter(uniques(ref=>ref.fileId)). // create a function uniques that only returns true for the first instance of fileId NOTE your code also used fieldId where it looks like it should use fileId
   forEach(ref=>{ 
      ... your original logic
   });
