Missing or invalid. request() method: wallet_addEthereumChain

[dingcxx]

I use modal-react-native in my app

this is my sessionParams :

export const MethodName = {
    addNet: 'wallet_addEthereumChain',
    switchNet: 'wallet_switchEthereumChain',
    sign: 'eth_sign',
    getChain: 'eth_chainId',
    sendTransaction: 'eth_sendTransaction',
    // signTransaction: 'eth_signTransaction',
    // signTypedData: 'eth_signTypedData',
    personalSign: 'personal_sign',
}

export const SUPPORT_NETs = [BSC, ETH, Goerli, TESTNET_BSC, zkSync_testnet, zkSync_mainnet]

    const OPTION_CHAINS = SUPPORT_NETs.filter((value) => value.networkId !== 1).map(
        (value) => `eip155:${value.networkId}`,
    )

    const OPTION_METHODS = [...Object.values(MethodName)]
    const REQUIRED_METHODS = ['eth_sendTransaction', 'personal_sign']
    const REQUIRED_EVENTS = ['chainChanged', 'accountsChanged']
    const sessionParams = {
        namespaces: {
            eip155: {
                methods: REQUIRED_METHODS,
                chains: ['eip155:1'],
                events: REQUIRED_EVENTS,
                rpcMap:{},
            },
        },
        optionalNamespaces: {
            eip155: {
                methods: OPTION_METHODS,
                chains: OPTION_CHAINS,
                events: REQUIRED_EVENTS,
                rpcMap: PRC_LISTs,
            },
        },
    }

rainbow wallet connected success

but when I request wallet_addEthereumChain receive error:

 {"context": "client"} Missing or invalid. request() method: wallet_addEthereumChain.

the session.namespaces maybe not include wallet_addEthereumChain , optionalNamespaces not useful.

hey @dingcxx

rainbow does not support adding custom networks & rpcs, which is the issue here. wallet_switchEthereumChain should have what you need

that being said we are updating our WC integration to better handle this case. should be live end of next week

thanks,
