Steps to reproduce

update " Vue CLI " => general setting "PublicPath" 's default value,then build error

What is expected?

according to the recommended configuration on the official website, I modified the value of publicPath ，

What is actually happening?

After modification, the compiler reported the following error。
error：Invalid options in vue.config.js: "publicPath" is not allowed

publicPath is a new opton in Vue CLI v3.3.
And you are still using v3.2.0

@vue/cli-service: ^3.0.4 => 3.2.0
