I have setup an email node with Oauth2 authentication, that side of it is working, I have got the access token ok.
I am getting an error on deploy when from the email node itself. ("ReferenceError: msg is not defined") This is only when I enable the Oauth2 authentication in the email node. so perhaps there is an issue in my message it is not properly defined for the email node? Ive tried a couple/alot of different format options havent managed as yet. What am I missing?
```auto
// Extract necessary values from input msg
let access_token = msg.oauth2Response.access_token;
// Create a new message object with only the necessary properties
let newMsg = {
payload: 'this is a dummy email',
topic: 'some title',
oauth2Response: {
access_token: access_token
}
};
// Return the new message object
return newMsg;
```
also tried this function to create the email.
```auto
// Add payload and topic properties to the msg object
msg.payload = 'this is a dummy email';
msg.topic = 'some title';
// Return the modified msg object
return msg;
```

@hadwll
I think this is a bug with the node - or at least its assumptions are incorrect.
@dceejay @Steve-Mcl
The node initializer is expecting an `msg` property - but during init, it will not exist?

This would explain the error occurring during deploy?
IMO adjusting SMTP auth methods should be occurring on `input` ?
certainly if auth values are to be taken from `msg`
I might be a little rusty - so forgive me, if i'm just talking rubbish

It certainly does look like a bug was introduced in [XOAuth2 for Email-In node by wooferguy · Pull Request #975 · node-red/node-red-nodes · GitHub](https://github.com/node-red/node-red-nodes/pull/975)
@hadwll - could you please [raise an issue](https://github.com/node-red/node-red-nodes/issues/new/choose) and link back to this thread?

yes, no problem, The issue is here [node-red-node-email, send node "ReferenceError: msg is not defined" on deploy · Issue #1054 · node-red/node-red-nodes · GitHub](https://github.com/node-red/node-red-nodes/issues/1054)
I wanted to ask then is this stopping my email sending?
As it is not working working for me and not presenting any error, I placed a catch node but it shows nothing as well.
