How to set Virtual Parameters

not.genieacs_scholar · March 21, 2025, 2:14pm

Hi everyone,

I have difficulty creating virtual parameters. I want to unify my device connection usernames in GenieACS under one virtual parameter. The script works without issues for most of devices, but not for all devices.

I created a virtual parameter as follows:

Name: “User”
Script:

let username;

let d = declare("Device.ManagementServer.Username", { value: Date.now() });
let igd = declare("InternetGatewayDevice.ManagementServer.Username", { value: Date.now() });

if (d.size && d.value[0]) {
  username = d.value[0];
} else if (igd.size && igd.value[0]) {
  username = igd.value[0];
}

if (typeof username === "string") {
  return { writable: true, value: [username, "xsd:string"] };
} else {
  return { writable: true, value: ["errusername", "xsd:string"] };
}

The error I get on some devices:

faultCode: "9003"
faultString: Invalid arguments
setParameterValuesFault: null

I also tried to return just a hard coded virtual parameter:

return {writable: false, value: ["testuser", "xsd:string"]};

I placed the parameter declaration in inform for testing, and tried setting it as:

declare("VirtualParameters.User", {path: Date.now(), value: Date.now()});

and as:

declare('VirtualParameters.User', {value: 1});

I would like to solve this for all devices (cpes). To have this in the device parameters
I tried deleting devices and retrying as well.
Thank you in all advance.

I’m not seeing from your vparam script any SPV’s. I don’t think the issue is with your vparam.
Enable debug for the CPE in question to figure out what the CPE doesn’t like. There are instructions on the forum on how to enable debug.

Hi akcoder,

Thank you for the reply, this is the debug log I get:

// Clear cached data model to force a refresh
clear("Device", now);

Any advice is much appreciated.

Thanks again.

You are missing the forest for the trees. The issue is not with your vparam or inform script.

Looks like when I delete everything but the Virtual Parameters from the inform provision the errors go away, and the VirtualParameter appears on the device.

So I suppose that I need to adjust the inform with if blocks to avoid this issue.
Something like the following pseudo code:

if (device_software_versions != "device_with_errors"){
declare....
}
// other shared code

Thanks.
