TypeScript errors with the ethers added functionality, like ethers.getSigners()

[Muhammad-Altabba]

Version of Hardhat

2.22.17

What happened?

After importing "@nomicfoundation/hardhat-toolbox"; at hardhat.config.ts, the hardhat commands work. But compiling the project with tsc gives errors with the ethers added functionality, like ethers.getSigners().

Minimal reproduction steps

The project was created with pnpm add -D hardhat and npx hardhat init using the template Create a TypeScript project.

Here is the tsconfig.json file:

{
  "compilerOptions": {
    "target": "es2020",
    "module": "commonjs",
    "esModuleInterop": true,
    "forceConsistentCasingInFileNames": true,
    "strict": true,
    "skipLibCheck": true,
    "resolveJsonModule": true,
    "outDir": "./build"
  }
}

And here is the hardhat.config.ts:

import { HardhatUserConfig } from "hardhat/config";
import '@nomicfoundation/hardhat-toolbox';

const config: HardhatUserConfig = {
  solidity: "0.8.28",
};

export default config;
