How can i get a field value in view mode using a client script?

Question

Hi I'm new to suitescript I've added a custom print button to the inventory item record, it works totally fine in edit mode but in view mode the client script can't get the field value for my print type, it returns an undefined value. it gives this error:

{"type":"error.SuiteScriptError","name":"MISSING_PDF_PARAMETERS","message":"Missing parameters required to generate PDF","stack":["renderAsPdf(N/render)","onRequest(/SuiteScripts/rtt/add-print-button/acq_sl_form_print.js:66)"],"cause":{"type":"internal error","code":"MISSING_PDF_PARAMETERS","details":"Missing parameters required to generate PDF","userEvent":null,"stackTrace":["renderAsPdf(N/render)","onRequest(/SuiteScripts/rtt/add-print-button/acq_sl_form_print.js:66)"],"notifyOff":false},"id":"","notifyOff":false,"userFacing":false}

i'm using a user event script

/**

• @NApiVersion 2.1
• @NScriptType UserEventScript
• @NModuleScope SameAccount */

define(['N/runtime', 'N/log', 'N/currentRecord'], function (runtime, log, currentRecord) {

    /**
    * beforeLoad event handler
    *
    * @gov 0
    *
    * @param context
    *        {Object}
    * @param context.newRecord
    *        {record} The new record being loaded
    * @param context.type
    *        {UserEventType} The action type that triggered this event
    * @param context.form
    *        {form} The current UI form
    *
    * @return {void}
    * @static
    * @function beforeLoad
    */
    function beforeLoad(scriptContext) {
        var objForm = scriptContext.form;
        objForm.clientScriptModulePath = "SuiteScripts/rtt/add-print-button/acq_cs_get_record.js";
        objForm.addButton({
            id: 'custpage_printbutton',
            label: 'Print Custom Label',
            functionName: 'onClickPrint'
        });
    }

    return {
        beforeLoad : beforeLoad
    }; 
});

a client script (to get the record and calling the suitelet page). In edit mode it gets normally the printType but i want it to work even if it's view mode.

/**

• @NApiVersion 2.1
• @NScriptType ClientScript
• @NModuleScope SameAccount */

define(['N/currentRecord'], function (currentRecord) {

    function pageInit(context) {

    }
    function onClickPrint(context) {
        var objRecord = currentRecord.get();
        var intRecId = objRecord.id;
        var printType = objRecord.getValue({
            fieldId: "custitem_acq_print_type"
        });
        console.log(printType);
        if(intRecId!= null && intRecId !="") {
            window.open('/app/site/hosting/scriptlet.nl?script=2553&deploy=1&printType=' + printType + '&recID=' + intRecId,'_blank');
        }
    }
    return {
        pageInit : pageInit,
        onClickPrint : onClickPrint
    }
}); 

and then a suitelet that renders my custom templates, based on which prinType is selected in the page

/**

• @NApiVersion 2.x
• @NScriptType Suitelet */

define(['N/render', 'N/file', 'N/record'],

function (render, file, record) {

    function onRequest(context) {

            if (context.request.parameters.printType && context.request.parameters.recID) {
                var intRecId = context.request.parameters.recID;
                var printType = context.request.parameters.printType;
                log.debug('print type', printType);
                log.debug('record id', intRecId);
                var renderer = render.create();
            
                var temp = record.load({
                    id: intRecId,

                });
                renderer.addRecord('record', temp);
    
                var linecount = temp.getLineCount({

                });
                log.debug(' righe ', linecount);
    
                var extraInformation = [];
                for (var i = 0; linecount > i; i++) {

                }
            
                renderer.addCustomDataSource({

                if(printType == 1){
                    renderer.setTemplateByScriptId("CUSTTMPL_ITEM_LABEL_A4");

                }
                

                // render PDF
                var finalPDF = renderer.renderAsPdf();
                log.debug('render page', finalPDF);
                /* newfile.folder = -15; // ID of folder where file created
                newfile.name = "itemLabel.pdf";
                var fileId = newfile.save(); */
                context.response.addHeader({
                    name: 'Content-Type', value: 'application/pdf'
                });
                context.response.addHeader({
                    name: 'Content-Disposition', value: 'inline; filename=itemLabel.pdf'
                });
                context.response.writePage(finalPDF);
            }
        }
    }

    return {
        onRequest: onRequest
    };
});

Sorry fo my english, if anyone knows a workaround to make this work in view also, it will be a major uplift to my workday.

I've tried to call the suitelet directly from the ue

function callForSuitelet(scriptContext){
            var rec = scriptContext.newRecord;
            var intRecId = newRecord.id;
            var recType = newRecord.type;
            var printType = rec.getValue({
                fieldId: "custitem_acq_print_type"
            });
            log.debug('record id', intRecId);
            log.debug('record type', recType);
            log.debug('print type', printType);

            if(intRecId!= null && intRecId !="") {
                var suiteletURL = url.resolveScript({
                    scriptId: "acq_sl_form_print.js",
                    deploymentId: "customdeploy_acq_sl_form_print",
                    params: { recordId: intRecId, recordType: recType, printType: printType },
                  });
                  document.location = suiteletURL;
                  log.debug("suiteletURL", suiteletURL);
            }
        }

but the button doesen't do anything at all

Client Scripts were not designed to work in View mode; thus, N/currentRecord does not load all of the record's data when used in View mode.

You will need to retrieve the value(s) of interest from the database via either N/record.load() or N/search.lookupFields(). lookupFields() will be quicker and use less governance, so I'd advise that you prefer that approach first.
