Hi,I’m working on creating a script to add a new connection on the TP-Link CPE XC220-G3v. I’ve put together this script, but unfortunately, it’s not working as expected. To troubleshoot, I’ve compared export files from a router with a new interface added via the web management interface and from a clean router to verify all the necessary parameters.I’d greatly appreciate any guidance or suggestions you might have—I’m still relatively new to GenieACS.Thank you in advance for your help!

script:

```auto
//new pppoe connection

You cannot depend on instance ids, they are not guaranteed.

`declare("Device.X_TP_GPON.Link.[]", null, {path:4});`

You’ve told GenieACS that you want 4 instances, but don’t specify the data for the 4 instances. Please see [this link for the syntax](https://forum.genieacs.com/t/working-with-objects-using-the-api/3415/2).

Your best bet is to build up the config you want on the CPE and replace the built-in config with that. Trying to create interfaces on the fly is going to be fraught with issues.
