bug: usePrepareContractWrite chainId validation not working

Is there an existing issue for this?

• I have searched the existing issues

Package Version

0.6.4

Current Behavior

I’m using the usePrepareContractWrite function in order to mint a NFT on Ethereum Mainnet.

In my MVP I’m calling the function as described here:

const {
    config,
    error: prepareError,
    isError: isPrepareError,
  } = usePrepareContractWrite({
    addressOrName: "0xaf0326d92b97df1221759476b072abfd8084f9be",
    contractInterface: ["function mint()"],
    functionName: "mint",
    chainId: 1,
  });

  const { data, error, isError, write } = useContractWrite(config);

When the user switches chains via Metamask extension, the write function invokes a transaction of 0 ETH to the specified contract address. The same behaviour occurs in the Docs page, while sometimes the ‘Mint’ button is disabled, occasionally when hopping chains it still tries to send a transaction when it’s on the wrong chain.

Expected Behavior

An actual error whenever the current user is not on the specified chain chainId . The write function should not execute an empty transaction.
