writeContract with dynamic abi

[yoshiwarab]

Hi! I have a use case that requires loading abi's dynamically from a remote source and am running into type issues when calling writeContract. I know type inference won't work in this case but would expect the typing to allow this call regardless. Assuming contractFunctionAbi here is an object of type AbiFunction, this code

await walletClient.writeContract({
    address: contractAddress,
    abi: [contractFunctionAbi],
    functionName: contractFunctionABI.name,
    account: "0x0000",
  });

produces the ts error for functionName Type 'string' is not assignable to type 'never'.ts(2322) contract.d.ts(13, 5): The expected type comes from property 'functionName' which is declared here on type 'WriteContractParameters<[AbiFunction], string, Chain | undefined, Account | undefined, Chain | undefined>'. Is this the expected behavior/is there some way around this or something else I'm missing. Thank you!

Should work if you cast it to as Abi: https://www.typescriptlang.org/play?target=99#code/JYWwDg9gTgLgBAbzgYygUwIYzQdQwG3zRgGF9g0A7GAGjgAsYYw6YBPMNOAQQCNg4AXzgAzKBBBwA5ADcKIKQChQkWIjggMwSpWJDR4ybPkB6ZPS2UAzksXII1+AHcCRUuSrwAvCnRZcrsRkFNQAFAiKcHAYyPYArtQAXNIADAAeKZlZ2Tm5efnZUjSRKBbayZraurQlMFAY1qowyYzMoQCUioKdii6EQR7UAHROUMDYJA51MTDhJRgAJgvoVlbJUukFW9tbRfP8yQjCGFY8-MVRIgnIMMAOAHIYIGjrEE66UADyIntRMgRxF5wFKULrtIA

You shouldn't need to pass value for nonpayable functions though. We need to fix up the type so it's not required for type Abi casted ABIs.

Ah, that's easy enough 😅, thank you!
