HTTP authentication fails with TypeError

[dirichs]

Using hessian-proxy with node.js v6.10.0, I get a TypeError when trying to establish a connection secured by BASIC authentication:

TypeError: First argument must be a string, Buffer, ArrayBuffer, Array, or array-like object.
at fromObject (buffer.js:262:9)
at Function.Buffer.from (buffer.js:101:10)
at new ClientRequest (_http_client.js:112:27)
at Object.exports.request (http.js:31:10)
at Object.exports.request (https.js:199:15)
at Proxy.invoke (/project/node_modules/hessian-proxy/lib/proxy.js:58:38)
at Object. (/project/lib/hessian-adapter.js:10:8)
at Module._compile (module.js:570:32)
at Object.Module._extensions..js (module.js:579:10)
at Module.load (module.js:487:32)

The problem is caused by the interpretation of options.auth in http.ClientRequest. It should be of the form "login:password", but instead Proxy.invoke supplies an object {"user":"login","pass":"password","sendImmediately":true}. This can be seen in proxy.js line 50-56:

    if (this.username) {
        options.auth = {
            user: this.username,
            pass: this.password,
            sendImmediately: true
        };
    }

Replacing these lines with

    if (this.username)
        options.auth = this.username + ":" + this.password;

resolves the issue.

Kind regards,
