Viem Version

2.18.8

Current Behavior

You can pass incorrect values for args in encodeFunctionData without a type error

Expected Behavior

A type error just like if you use the abi field directly without using prepareEncodeFunctionData

Steps To Reproduce

You can see if I use prepareEncodeFunctionData, there is no type error detected

const constInputData = prepareEncodeFunctionData({
  abi: [
    {
      inputs: [{ internalType: 'string', name: 'input', type: 'string' }],
      name: 'convertedPaimaData',
      outputs: [],
      stateMutability: 'nonpayable',
      type: 'function',
    },
  ],
});

const foo = encodeFunctionData({
  ...constInputData,
  args: [1], // note: wrong data, but no error!
});

However, if I inline the abi directly, it properly detects the error

const foo = encodeFunctionData({
  abi: [
    {
      inputs: [{ internalType: 'string', name: 'input', type: 'string' }],
      name: 'convertedPaimaData',
      outputs: [],
      stateMutability: 'nonpayable',
      type: 'function',
    },
  ],
  args: [1], // error working properly as expected: Type 'number' is not assignable to type 'string'
});
