    User.findOrCreate({ exampleId: profile.id }, function (err, user) {

The values for the tokenURL and authorizationURL are found in the Cognito settings in the AWS Console User Pool and Cognito documentation.

You can obtain the domain name from the Cognito config in the AWS Console under Cognito->User Pools->App Integration->Domain Name and tack on the endpoints from the documentation as follows. For example:

authorizationURL: 'https://your-domain-prefix.auth.us-east-1.amazoncognito.com/oauth2/authorize',

tokenURL: 'https://your-domain-prefix.auth.us-east-1.amazoncognito.com/oauth2/token',
