res.render doesn't render correctly after 1023 characters - node.js

Question

I have a parent Express app, and a Ghost app as a child app, using Ghost as an npm module here.
I routed Ghost to be rendered at http://localhost:9000/blog. All the configuration works fine (Ghost will throw an error if the basic configuration isn't being provided correctly).
Here is my Ghost startup code
ghost({
config: path.join(__dirname, '/config/ghost.config.js')
}).then(function (ghostServer) {
app.use(ghostServer.config.paths.subdir, ghostServer.rootApp);
ghostServer.start(app);
});
here is my Ghost config
// # Ghost Configuration
// Setup your Ghost install for various [environments](http://support.ghost.org/config/#about-environments).
// Ghost runs in `development` mode by default. Full documentation can be found at http://support.ghost.org/config/
var path = require('path'),
config;
config = {
// ### Production
// When running Ghost in the wild, use the production environment.
// Configure your URL and mail settings here
production: {
url: 'http://my-ghost-blog.com',
mail: {},
database: {
client: 'sqlite3',
connection: {
filename: path.join(__dirname, '/content/data/ghost.db')
},
debug: false
},
server: {
host: '127.0.0.1',
port: '2368'
}
},
// ### Development **(default)**
development: {
// The url to use when providing links to the site, E.g. in RSS and email.
// Change this to your Ghost blog's published URL.
url: 'http://localhost:9000/blog/',
// Example mail config
// Visit http://support.ghost.org/mail for instructions
// ```
// mail: {
// transport: 'SMTP',
// options: {
// service: 'Mailgun',
// auth: {
// user: '', // mailgun username
// pass: '' // mailgun password
// }
// }
// },
// ```
// #### Database
// Ghost supports sqlite3 (default), MySQL & PostgreSQL
database: {
client: 'sqlite3',
connection: {
filename: path.join(__dirname, '../blog/data/ghost-dev.db')
},
debug: false
},
// #### Server
// Can be host & port (default), or socket
server: {
// Host to be passed to node's `net.Server#listen()`
host: '127.0.0.1',
// Port to be passed to node's `net.Server#listen()`, for iisnode set this to `process.env.PORT`
port: '9000'
},
// #### Paths
// Specify where your content directory lives
paths: {
contentPath: path.join(__dirname, '../blog/')
}
},
// **Developers only need to edit below here**
// ### Testing
// Used when developing Ghost to run tests and check the health of Ghost
// Uses a different port number
testing: {
url: 'http://127.0.0.1:2369',
database: {
client: 'sqlite3',
connection: {
filename: path.join(__dirname, '/content/data/ghost-test.db')
}
},
server: {
host: '127.0.0.1',
port: '2369'
},
logging: false
},
// ### Testing MySQL
// Used by Travis - Automated testing run through GitHub
'testing-mysql': {
url: 'http://127.0.0.1:2369',
database: {
client: 'mysql',
connection: {
host : '127.0.0.1',
user : 'root',
password : '',
database : 'ghost_testing',
charset : 'utf8'
}
},
server: {
host: '127.0.0.1',
port: '2369'
},
logging: false
},
// ### Testing pg
// Used by Travis - Automated testing run through GitHub
'testing-pg': {
url: 'http://127.0.0.1:2369',
database: {
client: 'pg',
connection: {
host : '127.0.0.1',
user : 'postgres',
password : '',
database : 'ghost_testing',
charset : 'utf8'
}
},
server: {
host: '127.0.0.1',
port: '2369'
},
logging: false
}
};
module.exports = config;
So basically, when I go to http://localhost:9000/blog, it isn't being rendered at all. Nothing. I was using Chrome and also testing it using Safari. Also tested those two without JavaScript turned on.
And then I try to do curl http://localhost:9000/blog, and try using a requester app (like Postman) and they returned the correct html string. I also tried to do a curl using the user agent as Chrome and as Safari, it also returns the correct html.
I traced down to ghost node_modules, and the renderer is in ghost > core > server > controllers > frontend > index.js in this line res.render(view, result)
I changed the res.render to be like this
res.render(view, result, function(err, string) {
console.log("ERR", err);
console.log("String", string);
res.send(string);
})
and there is no error, it logs the current string, but it doesn't render anything on the browser.
I tried curl, postman, works, but browser doesn't work.
then I tried to send a hello world string, it works, the browser rendered it.
Then I add the string length one by one, and it turns out, any str.length < 1023 will be able to be rendered by the browser, but once it get past that, it doesn't.
And I tried in my parent Express app, it is able to send string which length is more than 1023, and if I use the ghost module as a standalone, it also able to send string more than 1023.
So something must have happened between those two, but I don't know how to debug this.
Please help
