usePrepareContractWrite fails for payable contract if args has many key-value pairs

[Lactantius]

I have a contract function that takes several values in a struct, and I want to interact with it with usePrepareContractWrite:

const { config } = usePrepareContractWrite({
  address: contractAddress,
  abi: [
    {
      inputs: [
        {
          components: [
            {
              internalType: "uint256",
              name: "tokenAmount",
              type: "uint256",
            },
            {
              internalType: "string",
              name: "tokenCode",
              type: "string",
            },
            // More arguments...
          ],
          internalType: "struct Test",
          name: "test",
          type: "tuple",
        },
      ],
      name: "test",
      outputs: [
        {
          internalType: "uint256",
          name: "",
          type: "uint256",
        },
      ],
      stateMutability: "payable",
      type: "function",
    },
  ],
  functionName: "test",
  args: [
    {
      tokenAmount: Utils.parseEther(String(formik.values.amount)),
      tokenCode: "MATIC",
      // More arguments...
    },
  ],
  overrides: {
    value: Utils.parseEther(String(formik.values.amount)),
    gasLimit: 500000,
  },
});
console.log(formik.values.amount);
console.log(config);
const { write } = useContractWrite(config);
console.log(write);

This will work as written, but when I start adding more key-value pairs to args then I get invalid BigNumber value (argument="value", value=undefined, code=INVALID_ARGUMENT, version=bignumber/5.7.0, and write is undefined unless value and tokenAmount are 0. I can always use two values in args, but the exact number I can add before failure seems to vary.

This is using Next and Wagmi 0.9.6 (using older version because of ConnectKit) and Next 13.0.6.

Everything looks correct. I would double check that Utils.parseEther(String(formik.values.amount)) is doing what you think it is. The error you posted makes it seems like an error is happening at that point with ethers.

[Lactantius]

Thanks. Logging the request when amount is 1 gives value: BigNumber {_hex: '0x0de0b6b3a7640000', _isBigNumber: true}.
Logging Utils.parseEther(String(formik.values.amount)).toString(); gives 1000000000000000000.

I stumbled upon the same error. The actual cause for it was my args' struct was defined incorrectly, but the error referred to txn's value being wrong for some reason.
It would have been faster for me to debug if the error was accurate.

Agree about error messages. Unfortunately this is an ethers error. Have a major update coming soon that will make error messages (and a load of other things) significantly better.

[Lactantius]

Thanks. I did get it working properly with plain ethers; I will double-check what I had for Wagmi.
