why TaskType.MAP_REDUCE can not be run without params ?

AI generated answer (using internal Slack threads):

The

TaskType.MAP_REDUCE

cannot be run without params because the parameters are used to pass data between scripts in NetSuite. When you create a Map/Reduce script, you often need to pass parameters from the script that initiates the task to the Map/Reduce script itself. These parameters are used to control the behavior of the Map/Reduce script or to provide it with the data it needs to process. In the context of SuiteScript, when you create a Map/Reduce task using

task.create({taskType: task.TaskType.MAP_REDUCE})

, you can pass parameters to it using the

params

property. For example:

javascript
let mrTask = task.create({
        taskType: task.TaskType.MAP_REDUCE,
        scriptId: "customscript873",
        deploymentId: "customdeploy2",
        params: {
          id_input: params.selectfield,
        },
});

In the Map/Reduce script, you can then retrieve these parameters using the

runtime.getCurrentScript().getParameter()

method. For example:

javascript
var scriptObj = runtime.getCurrentScript().getParameter("id_input");
log.debug(scriptObj);

However, it's important to note that these parameters must be defined on the script record in the NetSuite UI. If they are not defined, you will not be able to retrieve them in the Map/Reduce script, and they will be

undefined
