Good day developers. I´m receiving this error from webpack in my console:

(node:11612) UnhandledPromiseRejectionWarning: TypeError: Cannot read property 'compiler' of undefined

(node:11612) UnhandledPromiseRejectionWarning: Unhandled promise rejection. This error originated either by throwing inside of an async function without a catch block, or by rejecting a promise which was not handled with .catch(). To terminate the node process on unhandled promise rejection, use the CLI flag `--unhandled-rejections=strict` (see https://nodejs.org/api/cli.html#cli_unhandled_rejections_mode). (rejection id: 1)
(node:11612) [DEP0018] DeprecationWarning: Unhandled promise rejections are deprecated. In the future, promise rejections that are not handled will terminate the Node.js process with a non-zero exit code.

This ocurred after updating my webpack, webpack-cli and webpack-dev-server. Current versions are:

{
 ...
  "devDependencies": {
    ...,
    "prettier": "2.1.2",
    "sass": "1.32.2",
    "sass-loader": "10.1.0",
    "style-loader": "2.0.0",
    "ts-loader": "8.0.11",
    "ts-node": "9.0.0",
    "typescript": "4.0.5",
    "webpack": "5.68.0",
    "webpack-cli": "4.9.2",
    "webpack-dev-server": "4.9.0"
  }
}

after this update i delete my node_module package and the package_lock.json ones, thus after running npm install they were rebuild , but still this error persists.

Could someone give me an idea about why this error? Thanks in advance!!
