api.query.nicks.nameOf() method is broken

const provider = new WsProvider('wss://kusama-rpc.polkadot.io/');
const api = await ApiPromise.create({ provider });

const value = await api.query.nicks.nameOf(
   'HeCK315sYXruJvZKB5uXtEBnpWwYHFaKfNNZ54G76Qr7Nkn' //Validator stash ID
);

on calling namesOf() method results in the below error Error: FATAL: Unable to initialize the API: createType(Percent):: Unable to find plain type for {"info":6,"type":"Percent"}

The API supports anything on the metadata - so some chains, when they have the module included, will have nicks support. Kusama is not one of those. The API will never have chain-specific details in the CHANGELOG or anything specific. It is decorated by the chain metadata.

If you want chain-specific details, follow the specific chain, for Kusama that is the https://github.com/paritytech/polkadot repo.

TL;DR This is nothing JS or API related, the chain does not have the module.

@bhaskarSingh nicks were removed on Kusama in favor of the identity module
