Account Class Hash in wallet_addStarknetChain

[rsodre]

Hello,

I'm adding a custom network (local and L3) to ArgentX from my dapp using wallet_addStarknetChain. There is no specification for account class hash in AddStarknetChainParameters, but it is important to specify it.

Trying to pass accountClassHash or classHash does not have any effect (just being hopeful...):

const params = {
  "id": "LOCAL_KATANA",
  "chainId": "LOCAL_KATANA",
  "chainName": "Katana Local",
  "baseUrl": "http://localhost:5050",
  "rpcUrl": "http://localhost:5050",
  "rpcUrls": ["http://localhost:5050"],
  "nativeCurrency": {
    "address": "0x049d36570d4e46f48e99674bd3fcc84644ddd6b96f7c741b1562b82f9e004dc7",
    "name": "Ether",
    "symbol": "ETH",
    "decimals": 18
  },
  "accountClassHash": "0x029927c8af6bccf3f6fda035981e765a7bdbf18a2dc0d630494f8758aa908e2b",
  "classHash": "0x029927c8af6bccf3f6fda035981e765a7bdbf18a2dc0d630494f8758aa908e2b"
}
window?.starknet?.request({ type: 'wallet_addStarknetChain', params })

Looking at ArgentX source code, it looks like you should accept the class hash in accountImplementation, but it results a strangeZodError. But something is happening! Only bugged, it seems

}
window?.starknet?.request({ type: 'wallet_addStarknetChain', params })

the error...
