Bug Report

Describe the bug

Our company got our own babel preset which is similar to create-react-app preset, we always use it for build and compiling, I have removed the code which make use of that preset, but I found our preset could not work together with babel-plugin-export-metadata

To Reproduce

1. git clone https://github.com/huchenme/docz-v1-issue-demo
2. yarn install (need to use yarn)
3. yarn start

 error  in ./packages/core/Button/index.js

Module build failed (from ./node_modules/docz-core/node_modules/babel-loader/lib/index.js):
TypeError: @babel/template placeholder "NAME": Property declaration of ExportDefaultDeclaration expected node to be of a type ["FunctionDeclaration","TSDeclareFunction","C

I'm having the same issue for @babel/plugin-proposal-export-default-from, a plugin that my codebase depends on.

TypeError: @babel/template placeholder "NAME": Property declaration of ExportDefaultDeclaration expected node to be of a type ["FunctionDeclaration","TSDeclareFunction","ClassDeclaration","Expression"] but instead got null
