I cannot use SNICallback

Question

I couldn't manage using SNICallback on createServerfunction. When I try the below codes I get an error as Missing PFX or certificate + pricate key.

How can I solve this issue?

var fs = require('fs'),
      tls = require('tls'),
      https = require('https');

var certs = {
    "safe.myDomain.com": {
        key: fs.readFileSync('../SSL/safe/private/key.pem'),
        cert: fs.readFileSync('../SSL/safe/certs/cert.pem') 
    },
    "api.myDomain.com": {
        key: fs.readFileSync('../SSL/api/private/key.pem'),
        cert: fs.readFileSync('../SSL/api/certs/cert.pem')   
    }
}

var httpsOptions = {
    SNICallback: function(hostname, cb) {
      var ctx = tls.createSecureContext(certs[hostname])
      cb(null, ctx])
    }
}

https.createServer(httpsOptions).listen(1443, function() {
    console.log('HTTPS server is listening on port 1443')
})

SNICallback works great in NodeJS. I use it in production all the time. Here is a Stackoverlow answer with a detailed example of how to make it work.

The options to https.createServer must include key and cert as they are required. Even though that set won't be used if SNI provides a hostname.

See tls.createServer where it marks key and cert as required. (Linked from https.createServer.)
