如何使用打字稿中的自定義結構呼叫外部合約函式

我有這個基本的契約：

//SPDX-License-Identifier: Unlicense
pragma solidity ^0.8.4;

import "hardhat/console.sol";

contract Greeter {
   struct Greeting {
       uint8 id;
       string text;
   }

   Greeting[] public greetings;

   string private greeting;

   constructor(string memory _greeting) {
       greeting = _greeting;
   }

   function greet() public view returns (string memory) {
       return greeting;
   }

   function setGreeting(string memory _greeting) public {
       greeting = _greeting;
   }

   function setGreetings(Greeting[] calldata _greetings) external {
       for (uint16 i = 0; i < _greetings.length; i++) {
           greetings.push(_greetings[i]);
       }
   }
}

我嘗試setGreetings從以下位置撥打電話ethers.js：

const Greeter = await ethers.getContract("Greeter")
await Greeter.setGreetings([[0, "Hello, Hardhat!"]]);

但我收到：

Error: missing argument: passed to contract (count=0, expectedCount=1, code=MISSING_ARGUMENT, version=contracts/5.5.0)

雖然我確實設法setGreeting用字元串輸入呼叫：

await Greeter.setGreeting("Hello, Hardhat!");
expect(await Greeter.greet()).to.equal("Hello, Hardhat!");

您可以使用以下程式碼作為 setGreetings 的測試：

import { BigNumber } from "ethers";
import { ethers } from "hardhat";

describe("Greeter", function () {
 it("Should set greetings", async function () {
   const Greeter = await ethers.getContractFactory("Greeter");
   const greeter = await Greeter.deploy("Hello, world!");
   await greeter.deployed();

   const greetings = {
     id: BigNumber.from(0),
     text: "Hello, Hardhat!",
   }
   const setGreetingsTx = await greeter.setGreetings([greetings]);
   // wait until the transaction is mined
   await setGreetingsTx.wait();
 });
});
