Error initializing WalletConnect SDK [TypeError: Cannot read property 'getDefaultChain' of undefined]

Describe the bug
Getting the following error while trying to implement WC modal in react-native for Solana:

 INFO  {"context": "core"} Core Initialization Success
 INFO  {"context": "core"} {"context": "core/expirer"} Emitting expirer_deleted
 INFO  {"context": "client"} SignClient Initialization Success
 --> ERROR  Error initializing WalletConnect SDK [TypeError: Cannot read property 'getDefaultChain' of undefined]

Ethereum one works fine. What should I do to support Solana? I got the chain id from your SUPPORTED_CHAINS.md file

WalletConnectModal implementation (react native):

import { getSignPayload } from '~/store/addressBook/web3/AddressBookWeb3Utils';
import { actions } from '~/store/redux';
import { Steps } from '../ui/Steps';

export const WalletConnect = () => {
  const { open, isConnected, provider, address } = useWalletConnectModal();
  const [WalletConnectModal, setWalletConnectModal] = useState<((config: Props) => JSX.Element) | null>(null);
  const web3Provider = useMemo(() => (provider ? new ethers.providers.Web3Provider(provider) : undefined), [provider]);

  useEffect(() => {
    const loadWalletConnect = async () => {
      try {
        const { WalletConnectModal: WalletConnectModalComp } = await import('@walletconnect/modal-react-native');
        setWalletConnectModal(() => WalletConnectModalComp);
      } catch (error) {
        console.error('Failed to load WalletConnectModal:', error);
      }
    };

    setTimeout(loadWalletConnect, 500);
  }, []);

  const sign = async () => {
    if (!address) return;
    const signature = await web3Provider?.send('personal_sign', [getSignPayload(), address]);
    // make use of signature
  };

  const disconnect = () => {
    provider?.disconnect();
  };

  const getContent = () => {
    if (!WalletConnectModal) {
      return <Steps.Loading />;
    }

    if (isConnected) {
      return <Steps.Connected onPressOpenWallet={sign} onPressDisconnect={disconnect} />;
    }

    return <Steps.NotConnected onPressOpenWallet={open} />;
  };

  return (
    <>
      {getContent()}
      {WalletConnectModal ? (
        <WalletConnectModal
          projectId={WALLET_CONNECT_PROJECT_ID}
