Question

[webpack-cli] Invalid configuration object. Webpack has been initialized

``` using a configuration object that does not match the API schema.
 - configuration.devtool should match pattern "^(inline-|hidden-|eval-)?(nosources-)?(cheap-(module-)?)?source-map$".
   BREAKING CHANGE since webpack 5: The devtool option is more strict.
   Please strictly follow the order of the keywords in the pattern.
 - configuration.node should be one of these:
   false | object { __dirname?, __filename?, global? }
   -> Include polyfills or mocks for various node stuff.
   Details:
    * configuration.node has an unknown property 'setImmediate'. These properties are valid:
      object { __dirname?, __filename?, global? }
      -> Options object for node compatibility features.
    * configuration.node has an unknown property 'dgram'. These properties are valid:
      object { __dirname?, __filename?, global? }
      -> Options object for node compatibility features.
    * configuration.node has an unknown property 'fs'. These properties are valid:
      object { __dirname?, __filename?, global? }
      -> Options object for node compatibility features.
    * configuration.node has an unknown property 'net'. These properties are valid:
      object { __dirname?, __filename?, global? }
      -> Options object for node compatibility features.
    * configuration.node has an unknown property 'tls'. These properties are valid:
      object { __dirname?, __filename?, global? }
      -> Options object for node compatibility features.
    * configuration.node has an unknown property 'child_process'. These properties are valid:
      object { __dirname?, __filename?, global? }
      -> Options object for node compatibility features.
