Error after installing updated sendgrid-django package

[cesarmarroquin]

I am getting an issue on my python 3.5 and Django 1.10 project. I uninstalled sendgrid and sendgrid-django from my list of packages, and then reinstalled sendgrid-django and I now get a HTTP Error 400: Bad Request error when I try to send mail.

When i check my packages it shows that sendgrid is now 3.6.3 and sendgrid-django is 4.0.1. Sendgrid used to be 1.4.0 and sendgrid-django was 2.0.0 It was working before I installed the new updated versions.

My code is this below
mail = EmailMultiAlternatives( subject="Your Subject", body="a new application was created!", from_email="[email protected] <[email protected]>", to=["[email protected]"], headers={"Reply-To": "[email protected]"} ) mail.send()

Ive been trying to figure out but cant see what is causing the error. I even went as far as clearing my virtual enviroment locally, and reinstalling my packages and that didnt work.

@cesarmarroquin
just tested on my project, everything is working:

(example.com) vagrant@vagrant-ubuntu-trusty-64:$ python -V
Python 3.5.2
(example.com) vagrant@vagrant-ubuntu-trusty-64:$ pip freeze | grep sendgrid
sendgrid==3.6.3
sendgrid-django==4.0.1

(example.com) vagrant@vagrant-ubuntu-trusty-64:$ pip freeze | grep Django
Django==1.10.2

@cesarmarroquin can you share the actual body of the error you are seeing?

Got same error, looks like Reply-To header leads to error:

{"errors":[{
"message":"Header can not be one of the reserved keys. Refer to documentation link.",
"field":"headers.Reply-To",
"help":"http://sendgrid.com/docs/API_Reference/Web_API_v3/Mail/errors.html#message.headers"}
]}
