state not being sent

<your detailed question and code samples go here> For some reason my state parameters are not being places into the final url on generateAuthUrl().

My client id, secrets, access type, scopes, and redirect_uri are all generated correctly,

using this code:

let url = this.client.generateAuthUrl({
            // 'online' (default) or 'offline' (gets refresh_token)
            access_type: 'offline',
            // If you only need one scope you can pass it as a string
            scope: SCOPES,
            // Optional property that passes state parameters to redirect URI
            state: {foo: "bar", email: emailAddress, "test": "one"}
        });

I get

https://accounts.google.com/o/oauth2/auth?access_type=offline&scope=https%3A%2F%2Fmail.google.com%2F&state=&response_type=code&client_id=xxx.apps.googleusercontent.com&redirect_uri=http%3A%2F%2Flocalhost%3A9000%2Foauth2callback%2Fgoogle

Stringifying and enconding state object did the trick as @matkoklaic mentioned.

This should be included in the documentation.

Just make sure to stringify and encode state object passed to generateAuthUrl function: state: encodeURIComponent(JSON.stringify(state)).
