类型的参数＆＃x27;缓冲区的参数不能分配给类型的参数＆＃x27; String |数字| bn＆＃x27;

我有一个打字稿项目。该项目中的功能是以下函数：

import { hexToBytes, toHex } from 'web3-utils'

const signMessage = (msg: Hash) => {
    //  msg is a keccak-256 hash
    //
    const hashed = Buffer.from(hexToBytes(msg))
    const prvKey = Buffer.from(process.env.PRIVATE_KEY, "hex")
    const { signature, recid } = ecdsaSign(hashed, prvKey)
    // add key recovery parameter
    const ethSignature = new Uint8Array(65)
    ethSignature.set(signature)
    ethSignature[64] = recid
    return toHex(Buffer.from(ethSignature))
  }

这是从

const ethSignature: Uint8Array
Argument of type 'Buffer' is not assignable to parameter of type 'string | number | BN'.
  Type 'Buffer' is missing the following properties from type 'BN': clone, toNumber, toArray, toArrayLike, and 81 more.ts(2345)

这里发生了什么，我该如何解决此问题？

I have a Typescript project. Within that project is the following function:

import { hexToBytes, toHex } from 'web3-utils'

const signMessage = (msg: Hash) => {
    //  msg is a keccak-256 hash
    //
    const hashed = Buffer.from(hexToBytes(msg))
    const prvKey = Buffer.from(process.env.PRIVATE_KEY, "hex")
    const { signature, recid } = ecdsaSign(hashed, prvKey)
    // add key recovery parameter
    const ethSignature = new Uint8Array(65)
    ethSignature.set(signature)
    ethSignature[64] = recid
    return toHex(Buffer.from(ethSignature))
  }

This is taken from here. In that context, the function works fine. However, VSCode semantic highlighting marks the final line of the function as an error and provides the following:

const ethSignature: Uint8Array
Argument of type 'Buffer' is not assignable to parameter of type 'string | number | BN'.
  Type 'Buffer' is missing the following properties from type 'BN': clone, toNumber, toArray, toArrayLike, and 81 more.ts(2345)

What is going on here, and how do I resolve this?
