Cannot read property 'normal' of undefined

[whu12yz]

when I upgrade to webpack@5.0.0-beta.22 I got this error. There is no resolvers in compiler.
happypack@5.0.1

var resolver = compiler.resolvers.normal;
                                      ^

TypeError: Cannot read property 'normal' of undefined

It seems that not support webpack 5. Use thread-loader instead.
