The example hangs on [ EXECUTING: Generate Authorization Code]

[Zireael]

When I run the example and get to
http://localhost:3030/oauth/?grant_type=authorization_code&response_type=code&client_id=myClientId&redirect_uri=http://localhost:3030/client/app&state=myState
and submit with defailt username and password, the page hangs forever. There are no errors in the console. Possibly some .next() missing?

If you comment the code block of generateAuthorizationCode() function and run the example, it works.
I have tried that and its working. When you comment it the library checks if user has passed the above function or not, if not then it will execute its internal code block for generating authorization code and return that one.

Commenting out generateAuthorizationCode() worked for me too.
@14gasher, any chance you would be able to update this?

I am comparing these two examples that have a postgres DB implemented.
https://github.com/diogosouza/logrocket-oauth2-example
https://github.com/oauthjs/express-oauth-server/tree/master/examples/postgresql

Perhaps your Express-Shield would be a good candidate to add a Postgres backend?

Really appreciate the html example you have so far, thank you.

@14gasher had already found a way to fix this:

oauth-example/auth/oauth/model.js

Line 112 in e51401e

/*

.

    /* 
    For this to work, you are going have to hack this a little bit:
    1. navigate to the node_modules folder
    2. find the oauth_server folder. (node_modules/express-oauth-server/node_modules/oauth2-server)
    3. open lib/handlers/authorize-handler.js
    4. Make the following change (around line 136):

    AuthorizeHandler.prototype.generateAuthorizationCode = function (client, user, scope) {
      if (this.model.generateAuthorizationCode) {
        // Replace this
        //return promisify(this.model.generateAuthorizationCode).call(this.model, client, user, scope);
        // With this
        return this.model.generateAuthorizationCode(client, user, scope)
      }
      return tokenUtil.generateRandomToken();
    };
    */

As pointed out, this is a problem in the library. I've pointed it out several times to the community over there, but they still haven't fixed it.
