Nodejs app using Mailjet throwing a confusing error - node.js

Question

I'm building an app using Mailjet, and using their connection example.
app.get('/send',function(req,res){
...
var request = mailjet
.post("send")
.request({
<request stuff, email details>
});
request
.on('success', function (response, body) {
<handle response>
})
.on('error', function (err, response) {
<handle error>
});
Getting this error:
Unhandled rejection Error: Unsuccessful
at /home/ubuntu/workspace/node_modules/node-mailjet/mailjet-client.js:203:23
When I go to the Mailjet client and ask it to log the error, it tells me:
{ [Error: Unauthorized]
original: null,
...
Anyone have an idea of where I should start troubleshooting?
Update: saw this in the error output:
header:
{ server: 'nginx',
date: 'Thu, 02 Mar 2017 14:04:11 GMT',
'content-type': 'text/html',
'content-length': '20',
connection: 'close',
'www-authenticate': 'Basic realm="Provide an apiKey and secretKey"',
vary: 'Accept-Encoding',
'content-encoding': 'gzip' },
So it's not eating my API key and secret. Can anyone tell me how to set those as environmental variables in Cloud9?

Answer 1

You can set environment variables in ~/.profile. Files outside of the workspace directory /home/ubuntu/workspace aren't accessible for read-only users so people won't be able to see them.
In the terminal, you can do for example:
$> echo "export MAILJET_PUBLIC=foo" >> ~/.profile
$> echo "export MAILJET_SECRET=bar" >> ~/.profile
Then, you'll be able to access those variables in Node when using the connect method:
const mailjet = require ('node-mailjet')
.connect(process.env.MAILJET_PUBLIC, process.env.MAILJET_SECRET)
The runners (from the "run" button) and the terminal will evaluate ~/.profile and make the environment variable available to your app.
