I have custom parachain with pallet_proxy configured on it. I have created a pure proxy. But when I tried to add a second proxy to the anonymous account, I got the following error:
system.CallFiltered
It seems to be a pretty straightforward error. However, the runtime configuration doesn't filter any proxy transaction-related at all. In fact, I have even tried removing all the filters, but still fails. Am I missing something?
Indeed, my configuration for the pallet_proxy was incorrect; this piece of code was missing:
impl InstanceFilter<RuntimeCall> for ProxyType {
// missing function
fn is_superset(&self, o: &Self) -> bool {
match (self, o) {
(x, y) if x == y => true,
(ProxyType::Any, _) => true,
}
}
}
As far as I could understand, when proxy-related actions are performed through a proxy, it has to be checked that such proxy is a superset type. For example, it wouldn't make sense to be able to create an Any proxy type from a less restrictive proxy (e.g. Staking). Hope that makes sense.
