Proxy/Agent setting does not work (agent)

[sfakir]

The following lines to copy the values to parse fcmOptions.agent into an object instead copying it.

//copying the fcmOptions object to avoid problems in parallel calls 
var mFcmOptions = JSON.parse(JSON.stringify(self.fcmOptions));

workaround (but not really pretty)

    var agent = self.fcmOptions.agent;
    var mFcmOptions = JSON.parse(JSON.stringify(self.fcmOptions));
    mFcmOptions.agent = agent;
