Error: Empty from email address (required)

[guy-codefresh]

I'm using the latest npm module version and when I try, even the simplest test, I'm getting the following error:
Error: Empty from email address (required)

This is the example code we are testing.
Up until few days ago all was working

var sendgrid = require("sendgrid")(API_KEY);

sendgrid.send({
to: 'example@example.com',
from: 'other@example.com',
subject: 'Hello World',
text: 'My first email through SendGrid.'
}, function(err, json) {
if (err) { return console.error(err); }
console.log(json);
});

It looks like the upstream dependency request was updated today. Pinning it to the previous version 2.58.0 fixes things. Will roll out a new version locking it there until we can figure out what's up.

I just released version 1.9.1 with a pinned request version below 2.59.0. Will need to figure out what changed and write a better test to catch it.

Sorry for any trouble this caused you.

It looks like the _send method needs to be rewritten. It was originally created to build out req.form() before the next event loop pass.

From the docs

For advanced cases, you can access the form-data object itself via r.form(). This can be modified until the request is fired on the next cycle of the event-loop. (Note that this calling form() will clear the currently set form data for that request.)

It seems that the content-type is now not set when doing this via request/request#1650.
