Can't start craco - cannot read 'push' from undefined error

Hello! I was giving a try to this plugin, but I can't figure out how to make it run, here is the error:

C:\my-project>yarn start
yarn run v1.21.1
$ craco start

My .cracorc.ts configuration file looks like the following:

import { CracoConfig } from '@craco/craco'
const CracoRawLoaderPlugin = require('@baristalabs/craco-raw-loader')

export default {
  plugins: [
    {
      plugin: CracoRawLoaderPlugin,
      options: {
        test: /\.txt$/,
      },
    },
  ],
} as CracoConfig

(Also tried importing the plugin with import either as namespace or default, but without sucess)

Node version v14.17.0
