Nextjs HookWebpackError: Cannot set properties of undefined (setting 'type')-CodePudding

yarn run v1.22.19
$ next build

CodePudding user response：

I cloned your repository and made a build, it gave no error! I think it's a problem with your local configuration.

CodePudding user response：

It was a CSS syntax error, which didn't appear during development but only during build time. Keep that in mind to anyone who might see this.
