I am trying to load field values onto a purchase order record when the page is loaded. I was able to get the field values to populate on page Init but I changed it to beforeLoad to get it show in view mode. I started to receive the error: Cannot read property 'setValue' of undefined [at Object.beforeLoad (/SuiteScripts/beforeLoadPO.js345)] Are there any recommendations on how to get the field values to populate with beforeLoad?

/**
 * @NApiVersion 2.1
 * @NScriptType UserEventScript
 */
define(['N/record', 'N/log', "N/format"], (record, log, format) => {
   function beforeLoad(context){
    
    log.debug({
        title: "test",
        details: "Script Triggered This is the date" + d + "/n" + 
        "This is the formatted date: " + formattedDateString + 
        "This is the sale order date" + salesOrder 

    })
    context.currentRecord.setValue({
        fieldId: "duedate",
        value: new Date(),
        ignoreFieldChange: true
        
    })

    context.currentRecord.setValue({
        fieldId: "custbody_lf_expected_delivery_date",
        value: new Date(),
        ignoreFieldChange: true
    })

    context.currentRecord.setValue({
        fieldId: "custbody_lf_deadline_to_release",
        value: new Date(),
        ignoreFieldChange: true
    })

    // custbody_lf_exp_ship_date
    // context.

   
   }return{
    beforeLoad: beforeLoad
   }
});
