[webpack-cli] ValidationError: Invalid options object. Copy Plugin has been initialized using an options object that does not match the API schema.
- options[0] misses the property 'patterns'. Should be:
  [non-empty string | object { from, to?, context?, globOptions?, filter?, toType?, force?, flatten?, transform?, cacheTransform?, transformPath?, noErrorOnMissing? }, ...] (should not have fewer than 1 item)
