Prerender not serving up products - angularjs

Question

I am serving up angular pages from express. I cannot get prerender to serve up rendered pages for the products:
http://www.minilolo.com/?_escaped_fragment_=/products/Lolo-Pink
But other pages like this one are OK:
http://www.minilolo.com/?_escaped_fragment_=/products
I think I may need to add some express routes, but would like to know if I am on the right track. Thanks!
var express = require('express');
var path = require('path');
var favicon = require('serve-favicon');
var logger = require('morgan');
var cookieParser = require('cookie-parser');
var bodyParser = require('body-parser');
var app = express();
// uncomment after placing your favicon in /public
//app.use(favicon(path.join(__dirname, 'public', 'favicon.ico')));
app.use(logger('dev'));
app.use(bodyParser.json());
app.use(bodyParser.urlencoded({ extended: false }));
app.use(cookieParser());
app.set('view engine', 'ejs');
app.use(require('prerender-node').set('prerenderToken', 'xyz123'));
/**
* Development Settings
*/
if (app.get('env') === 'development') {
// This will change in production since we'll be using the dist folder
app.use(express.static(path.join(__dirname, '../client')));
// This covers serving up the index page
app.use(express.static(path.join(__dirname, '../client/.tmp')));
app.use(express.static(path.join(__dirname, '../client/app')));
// Error Handling
app.use(function(err, req, res, next) {
res.status(err.status || 500);
res.render('error', {
message: err.message,
error: err
});
});
}
/**
* Production Settings
*/
if (app.get('env') === 'production') {
// changes it to use the optimized version for production
app.use(express.static(path.join(__dirname, 'dist')));
// added to serve up products pages
app.use(function(req, res) {
// Use res.sendfile, as it streams instead of reading the file into memory.
res.sendfile(__dirname + '/dist/index.html');
});
// production error handler
// no stacktraces leaked to user
app.use(function(err, req, res, next) {
res.status(err.status || 500);
res.render('error', {
message: err.message,
error: {}
});
});
}
module.exports = app;
EDIT: I have tracked down the issue to prerender converting '?_escaped_fragment_=' into '#!'. Angular then doesn't know which route to use unless I have $locationProvider.hashPrefix('!') in place (which I don't want to use). I dont want the # prefix if it can be helped.

As explained on the following links:
https://github.com/prerender/prerender/issues/198
https://developers.google.com/webmasters/ajax-crawling/docs/specification?hl=en
The query from the search has '?_escaped_fragment_=' at the end of the path, rather than straight after the fqdn.
http://www.minilolo.com/?_escaped_fragment_=/products/Lolo-Pink <-- not this
http://www.minilolo.com/products/Lolo-Pink?_escaped_fragment_= <-- this!
