Are you sure that "file" is a valid parameter in "fetch"?
Maybe you want to use src-path instead?

I fixed the script; it runs, but doesn't do anything. I get a message in the logs:
"No new updates in this run (possibly empty result array)."
I'm also attaching the debug log. It connects to the group, receives the message, but nothing happens.

At first look, it seems that guess AI doesn’t know about deserialize command. data variable is string until it’s deserialized from JSON (using :parse command for data is wrong, is not meant for deserialization), also list type doesn’t exists so it is unnecessary to check such type - [:typeof $updates] = "list". There I stopped analyzing…
Yep, the "else" that outputs "No new updates in this run (possibly empty result array)." seems to be the one corresponding to this "if":
:if ([:typeof $updates] = "array" || [:typeof $updates] = "list") do={
so the first issue is in that condition.
Thanks everyone. The code works; the /delete wg command deletes the interface.
