SuiteScript 2 Email Invoices - netsuite

Question

Hi and I I am not a pain, I got help on sending a statement and that worked perfectly, but I need to send invoices with it but I can't find a method for that like I did for the statement. I find references to using a template file, then you have to store the file in the cabinet. I have to attach there to emails, what would you think the best way to do this?
Here is the other link, he gave a very helpful complete answer about sending statements. I should have asked him about invoices at the same time but I didn't think of it, apologies.
SuiteScript 2 can send pdf statements
added additional info
Ok I tried this but I am getting an error that doesn't make sense as I am using their templates.
"error.SuiteScriptError","name":"USER_ERROR","message":"Error Parsing XML: The reference to entity \"c\" must end with the ';' delimiter.",
require(['N/render', 'N/file', 'N/record'],
function(render, file, record) {
function renderRecordToPdfWithTemplate() {
var renderer = render.create();
renderer.setTemplateByScriptId("STDTMPLCUSTINVC");
var xml = renderer.renderAsString();
renderer.addRecord(record.Type.INVOICE, record.create({
type: record.Type.INVOICE,
id:415619
}));
var invoicePdf = renderer.renderAsPdf();
var foo = this;
}
renderRecordToPdfWithTemplate();
});
thanks for any help with this

Answer 1

Ok I found it thanks if anyone was looking for this for me. It is pretty straightforward, but like NetSuite always is, you have to find it. :)
the entityid is the invoice internalid the rest is easy, then just pass the file object to the email.
require( [ 'N/render', 'N/file', 'N/record' ],
function( render, file, record ) {
function renderRecordToPdfWithTemplate() {
var transactionFile = render.transaction({
entityId: 415619,
printMode: render.PrintMode.PDF
});
var foo = this;
}
renderRecordToPdfWithTemplate();
} );
thanks again
