Wagmi: 'connection.connector.getProvider is not a function'

[0xbid]

With some sites that use Wagmi hooks, the calls to hook will fail with connection.connector.getProvider is not a function', only while using Rabby wallet.

Describe the bug

Periodically, all functions from hooks (e.g. connect, writeContract / writeContractAsync) fails with connection.connector.getProvider is not a function.

Refreshing page fixes it.

It only occurs with Rabby wallet, Metamask stays connected always and does not run into the issue.

Steps To Reproduce

Nextjs 13+ SSR configured

wagmiConfig.ts

export const wagmiConfig = createConfig({
    // Setup chains
    chains: chains,
    transports: {
        [mainnet.id]: http(),
        [goerli.id]: http(),
        [sepolia.id]: http(),
        [holesky.id]: http()
    },

    // Enable SSR support (needs cookies)
    ssr: true,
    storage: createStorage({
        storage: cookieStorage
    }),

    connectors: [injected()]
});

Web3Provider.tsx

'use client';

// ...

const queryClient = new QueryClient();

const Web3Provider = ({
    children,
    initialState
}: {
    children: React.ReactNode;
    initialState: State;
}) => {
    return (
        <>
            <WagmiProvider config={wagmiConfig} initialState={initialState}>
                <QueryClientProvider client={queryClient}> {children}</QueryClientProvider>
            </WagmiProvider>
        </>
    );
};

layout.tsx

// ...
const initialState = cookieToInitialState(wagmiConfig, headers().get('cookie'));
This may also be relevant: I do not use any 3rd party connector (e.g. ConnectKit, Web3Modal, etc). I just do a simple:

'use client';

// ...

       const { connectors, connect } = useConnect();

        if (!isWalletConnected) {
            try {
                connect({ connector: connectors[0] });
            } catch (e) {
               // ...
            }
        }

• [X] I checked there isn't already an issue for the bug I encountered.

Anything else?

I think it would be really helpful to know more about how connection.connector.getProvider could occur from a dev perspective, e.g. what is going on. Then we can narrow down why it doesn't work with Rabby.
