"path" argument must be of type string

[blackbeario]

I am getting an undefined TypeError for the path argument. It seems similar to this issue #10, but in my case return loopbackSSL.startServer(app); follows my boot function. See below:

boot(app, __dirname, function (err) {
    if (err) throw err;
    // Start the server if `$ node server.js`.
    if (require.main === module) {
        app.io = require('socket.io')(loopbackSSL.startServer(app));
        require('socketio-auth')(app.io, {
            authenticate: function (socket, value, callback) {
                // We can log the user's info from the socket cookie
                // console.log(socket.handshake.headers.cookie);
                socket.client.accessToken = null;
                socket.client.userId = null;
                if (value && value.userId && value.id) {
                    // Value yields access token and userID.
                    var AccessToken = app.models.AccessToken;
                    // Get credentials sent by the client.
                    var token = AccessToken.findOne({
                        where: {
                            and: [{userId: value.userId}, {id: value.id}]
                        }
                    }, function (err, tokenDetail) {
                        if (err) throw err;
                        if (tokenDetail) {
                            // Add user Id to app connections.
                            socket.client.accessToken = tokenDetail;
                            socket.client.userId = value.userId;
                            callback(null, true);
                        } else {
                            callback(null, true);
                        }
                    });
                } else {
                    // Set to false to disconnect user.
                    callback(null, true);
                }
            },
            postAuthenticate: function (socket, data) {
                console.log("user connected User:", socket.client.userId ? socket.client.userId : "anonymous");
            }
        });
        app.io.on('connection', function (socket) {
            socket.on('disconnect', function () {
                console.log('user disconnected User:', socket.client.userId ? socket.client.userId : "anonymous");
            });
        });
    }
});

return loopbackSSL.startServer(app);

Here's my config (actual server replaced with myserver):

"httpMode": false,
  "certConfig": {
    "path": "/etc/ssl/myserver.com/",
    "key": "myserver.com.pem",
    "cert": "myserver.com.pem",
    "ca": [],
    "requestCert": false,
    "rejectUnauthorized": false
  },

The error reads:

I guess this could be something related to my boot function using socket.io, or an incorrect implementation of loopbackSSL.startServer(app);, which relates to #35. We need to have some examples of using this package with modified boot scripts and appStartEvents.

Furthermore, if I remove my server.js file contents completely and replace with the example server.js from the README, e.g.

var loopback = require('loopback');
var boot = require('loopback-boot');
var loopbackSSL = require('loopback-ssl');
 
var app = module.exports = loopback();
 
boot(app, __dirname, function(err) {
  if (err) throw err;
});
 
return loopbackSSL.startServer(app);

I get this error:

This ended up being because I was using config.test.json instead of config.json because I have separate environment configs, and I didn't have the loopback-ssl config in config.json.

So, this presents another issue, how to make loopback-ssl recognize the correct config file based on env settings. Currently, it seems it will only recognize config.json and not config.test.json, config.staging.json, or config.production.json.
