Troubles with types of universal send helper

[kostysh]

Hi,
to avoid code duplication I want to create a universal send helper that should accept contract ABI, function name and arguments.
But I suck at defining types for this function. The publicClient.simulateContract yells that type of functionName is incompatible and I do not understand how to fix it.

Maybe someone solved already the same?

Please take a look at the following code. Also, I have create a codesanbox with the same code: https://codesandbox.io/s/fervent-darwin-jsxs86?file=/src/index.ts:0-1305

import {
  Address,
  PublicClient,
  WalletClient,
  GetFunctionArgs,
  TransactionReceipt,
  BaseError,
  ContractFunctionRevertedError
} from "viem";
import { Abi } from "abitype";

/**
 * Universal send helper
 */
export const sendHelper = async <
  ContractAbi extends Abi | readonly [],
  FunctionName extends string
>(
  address: Address,
  abi: ContractAbi,
  functionName: FunctionName,
  args: GetFunctionArgs<ContractAbi, FunctionName>['args'],
  publicClient: PublicClient,
  walletClient: WalletClient,
  txCallback?: (txHash: string) => void
): Promise<TransactionReceipt> => {
  const [account] = await walletClient.getAddresses();

  try {
    const { request } = await publicClient.simulateContract({
      address,
      abi,
      functionName,
      args,
      account
    });

    const hash = await walletClient.writeContract(request);

    if (txCallback) {
      txCallback(hash);
    }

    return await publicClient.waitForTransactionReceipt({ hash });
  } catch (error) {
    if (
      error instanceof BaseError &&
      error.cause instanceof ContractFunctionRevertedError
    ) {
      const cause: ContractFunctionRevertedError = error.cause;
      throw new Error(
        cause.data?.errorName ?? "Unknown contract function revert error"
      );
    }

    throw error;
  }
};
