FYI, in case this helps some-one...

I resolved this after reviewing what the extension-wrapper script does. The 
extension scripts require a callback;

exports.getSIP = function(d, callback) {
        console.log("in getSIP with "+d);
        var ldap = require('ldapjs');
        let SIPParms = {
                "username": '5645195',
                "password": 'bleah'
        }
        callback(null, SIPParms);
}

(The 1st parameter in the callback is an error value)

Subject: RE: Virtual parameters


Hi,

I'm also struggling with this, except I'm trying to use an extension script 
rather than virtual parameters. The documentation refers to them as similar, 
but the extension section of the docs is TODO, and I can't find any examples 
anywhere.

The provision script looks this this..
let serial = declare("InternetGatewayDevice.DeviceInfo.SerialNumber", {value: 
1}); log("provision with "+serial.value[0]); let resp = ext("testext", "start", 
serial.value[0]); log("provision back from extension"); 
declare("InternetGatewayDevice.ManagementServer.Username", {value: 1},
  {value: resp.username});
declare("InternetGatewayDevice.ManagementServer.Password", {value: 1},
  {value: resp.password});

If I remove the extension, (and set static values) the provision works as 
expected. But when I call the extension, I get the following error; Channel has 
faulted; channel="default" retries=0 faultCode="timeout" 
faultMessage="Extension timed out"

The extension looks like this;
exports.start = function(d) {
 console.log("in ext script start with "+d);  let sipuser = "5645194";  let 
sippw = "bleah";  return {
  "username": sipuser,
  "password": sippw
 };
}

I get the log message, so it's being called, but the script really isn't doing 
enough to be actually timing out.
(Ultimately, my intention is to use the extension to retrieve SIP parameters 
from an LDAP directory, and provisioning them into the CPE)

Regards
Marc

Here's a sample script:

    declare("InternetGatewayDevice.ManagementServer.PeriodicInformEnabl

    declare("InternetGatewayDevice.DeviceInfo.ProductClass", {value:

1});
    declare("InternetGatewayDevice.DeviceInfo.Manufacturer", {value:
1});
    declare("InternetGatewayDevice.WANDevice.*.WANConnectionDevice.1.WA
NPPConnection.*.MACAddress", {value: 1});
    declare("InternetGatewayDevice.WANDevice.*.WANConnectionDevice.1.WA

    declare("InternetGatewayDevice.LANDevice.*.Hosts.Host.*.HostName",

    declare("InternetGatewayDevice.LANDevice.*.Hosts.Host.*.IPAddress",
{value: 1});
    declare("InternetGatewayDevice.LANDevice.*.Hosts.Host.*.MACAddress"
, {value: 1});

That's a bug that was recently fixed. Pull the latest changes.
