Library is not returning a valid RefreshToken

[ghost]

I'd receiving a valid accessToken, however the refreshToken is undefined!

I have no clue how to debug it. Any help? :)

Google does only return an refreshToken if offline access was requested [1]. You can tell passport to request offline access by adding accessType: 'offline' to the options passed to authenticate.

e.g. app.get('/auth/google', passport.authenticate('google', { accessType: 'offline' }));

Please also not that Google only gives you a refreshToken the first time a user approves your application.
To get a refresh token again you need to force Google to display the consent screen again. This can be done by passing approval_prompt: 'force' to the authenticate options.

I hope this helps.

I do have accessType: 'offline' setup.
Also, the approval_prompt: 'force' is not working.

I cloned this repo, put up my credentials and ran the oauth2 code under examples/ with still no luck.
Is it possible that it has to do with my app registered on google's console? Are there permissions I should do there or something?

Could you try to remove the authorization for the app in your google account.
This way google will ask you for authorization again. In that case I received a refreshToken.

You can revoke the authorization here: https://security.google.com/settings/security/permissions

Ah... so @jaredhanson has a different naming convention, it should be approvalPrompt with no underscore.

@jaredhanson this is kind-of misleading. Can we have all optiosn named like in the original google documentation

Now i'm getting a refresh token! Thanks :)
