attach a pdf to an email in meteor - pdf

Question

This Meteor server code tries to attach a pdf file but giving errors on server startup. I want avoid saving the file locally first.
it is using pascoual:pdfkit.
The error I am getting is:
Error: Message failed: 421 Timeout waiting for data from client.
Meteor doc point to mailcomposer documentation, but the issue is how to integrate the pdf doc in the attachments. Any ideas? Thanks
Meteor.startup(() => {
Invoice.email();
};
// invoice.js
use strict";
let PDFDocument = require ('pdfkit');
let metaData = {
'Title': 'Invoice',
'Author': 'myName',
};
export const Invoice = {
'make': function () {
let doc = new PDFDocument(metaData);
doc.text('my company').text('company number');
return doc;
},
'email': function () {
let inv = Invoice.make();
Email.send({
to: 'myemail#comp.com',
from: 'personal#company.com',
subject: 'Invoice',
text: ' Please see the attached invoice',
attachments: {
filename: 'invoice.pdf',
content: inv // <=== this is the issue
});
}
};

Answer 1

As per Documentation, the content definition is
content - String, Buffer or a Stream contents for the attachment
Link to mailcomposer documentation.
If I am not wrong the Invoice.make() is not returning expecting format of blob. Kindly check the Stream and type so that you know you get what you are creating.
