Type 'XXX' does not satisfy the constraint 'Idl'.

[AngouNin]

Hi, everyone.
I am testing my solana contract with anchor.
My anchor version is 2.9.0.
I run "anchor build" and then idl file was generated in /target directory.
But I can see following error in this code.

import * as anchor from "@coral-xyz/anchor";
import { Program } from "@coral-xyz/anchor";
import { PublicKey, SystemProgram } from "@solana/web3.js";
import { expect } from "chai";
import { XXX } from "../target/types/xxx";

describe("initialize_program", () => {
  // Configure the client to use the local cluster or devnet.
  anchor.setProvider(anchor.AnchorProvider.env());
  const program = anchor.workspace.XXX  as Program<XXX>;

So has an error.

Type 'XXX' does not satisfy the constraint 'Idl'.
Type 'XXX' is missing the following properties from type 'Idl': address, metadatats(2344)
