Please write a suitescript to create sales order from json

AI generated answer (using internal Slack threads):

Here is a basic example of how you can create a Sales Order from JSON using SuiteScript:

javascript
/**
 * @NApiVersion 2.x
 * @NScriptType Suitelet
 */
define(['N/record', 'N/error'], function(record, error) {
    function onRequest(context) {
        if (context.request.method === 'POST') {
            var salesOrderData = JSON.parse(context.request.body);
            try {
                var salesOrder = record.create({
                    type: record.Type.SALES_ORDER,
                    isDynamic: true
                });
                salesOrder.setValue({
                    fieldId: 'entity',
                    value: salesOrderData.customerId
                });
                for (var i = 0; i < salesOrderData.items.length; i++) {
                    salesOrder.selectNewLine({
                        sublistId: 'item'
                    });
                    salesOrder.setCurrentSublistValue({
                        sublistId: 'item',
                        fieldId: 'item',
                        value: salesOrderData.items[i].itemId
                    });
                    salesOrder.setCurrentSublistValue({
                        sublistId: 'item',
                        fieldId: 'quantity',
                        value: salesOrderData.items[i].quantity
                    });
                    salesOrder.commitLine({
                        sublistId: 'item'
                    });
                }
                var salesOrderId = salesOrder.save();
                context.response.write(salesOrderId);
            } catch (e) {
                throw error.create({
                    name: 'SALES_ORDER_CREATION_ERROR',
                    message: e.message
                });
            }
        }
    }
    return {
        onRequest: onRequest
    };
});

This script creates a new Sales Order record and sets the customer and line items based on the JSON data received in the POST request. The JSON data should be in the following format:

json
{
    "customerId": "123",
    "items": [
        {
            "itemId": "456",
            "quantity": "2"
        },
        {
            "itemId": "789",
            "quantity": "1"
        }
    ]
}
