无法评估脚本：当我上传 map/reduce 脚本时，我收到了后面的错误

Question

错误无法评估脚本：{"type":"error.SuiteScriptModuleLoaderError","name":"UNEXPECTED_ERROR","message":"syntax error (SS_SCRIPT_FOR_METADATA#11)","stack ":[]}

我是 suitescript 的新手，所以，我想知道 map/reduce 脚本是如何工作的，我复制了文档示例，但我收到了那个错误。

define(['N/file'], (file) => {
const PUNCTUATION_REGEXP = /[\u2000-\u206F\u2E00-\u2E7F\'!"#$%&\(\)\*\+,\-\.\/:;<=>\?@\ 
[\]\^_`\{\|\}~]/g;


function getInputData() {
return 'the quick brown fox \njumps over the lazy dog.'.split('\n');
}


function map(context) {

for (let i = 0; context.value && i < context.value.length; i++) {
  if (context.value[i] !== ' ' && !PUNCTUATION_REGEXP.test(context.value[i])) {

    context.write({
      key: context.value[i],
      value: 1,
    });
  }
}
}


function reduce(context) {

context.write({
  key: context.key,
  value: context.values.length,
});
}


function summarize(context) {

log.audit({
  title: 'Usage units consumed',
  details: context.usage,
});
log.audit({
  title: 'Concurrency',
  details: context.concurrency,
});
log.audit({
  title: 'Number of yields',
  details: context.yields,
});


let text = '';
let totalKeysSaved = 0;
context.output.iterator().each((key, value) => {
  text += (`${key} ${value}\n`);
  totalKeysSaved++;
  return true;
});

log.audit({
  title: 'Unique number of letters used in string',
  details: totalKeysSaved,
});


const fileObj = file.create({
  name: 'prueba_mapReduce_training_lk.txt',
  fileType: file.Type.PLAINTEXT,
  contents: text,
});

fileObj.folder = -15;
const fileId = fileObj.save();


log.audit({
  title: 'Id of new file record',
  details: fileId,
});
}

return {
getInputData,
map,
reduce,
summarize,
};
});

感谢您的帮助！

Answer 1

查看下面的标签，Map/Reduce 脚本需要它们：

/** *@NApiVersion 2.x *@NScriptType MapReduceScript */

Answer 2

Netsuite Suitescript 的语法与 Javascript 不完全相同。

导致问题的原因是 -

不要在定义变量时使用let。

输出迭代器循环将有一些更好的语法。（使用 => 会出错。）请确保 (${key} ${value}\n) 导致其出错。暂时用0代替

CORRECT SYNTAX-

context.output.iterator().each(function(key, value){
    text += 0; //Some issue with (`${key} ${value}\n`) [BAD SYNTAX]
    totalKeysSaved++;
    return true;
  });

始终包含 JSDoc

/** 
    *@NApiVersion 2.x 
    *@NScriptType MapReduceScript 
*/

遵循 return 语句的规则

return {
  getInputData:getInputData,
  map:map,
  reduce:reduce,
  summarize:summarize,
}

以上是我发现的问题，请使用下面的代码进行测试。为我工作。

/**

   *@NScriptType MapReduceScript

    function getInputData() {

    }
    
    
    function map(context) {
    
    for (i=0; (context.value && i) < context.value.length; i++) {

        context.write({
          key: context.value[i],
          value: 1,
        });
      }
    }
    }
    
    
    function reduce(context) {
