Environment

  • Linaria version:
    • @linaria/core 4.2.10
    • @linaria/shaker 4.2.11
    • @linaria/react 4.3.8
  • Bundler: webpack 5.75
  • Node.js version: v16.14.2
  • OS: MacOS 13.3.1

Description

When migrating my codebase to the latest Linaria, I encounter this error:

Cannot read properties of null (reading 'declarations')
    at NodePath._getKey (@babel+traverse@7.22.5/node_modules/@babel/traverse/lib/path/family.js)

I was able to narrow it down to one function, which I've included in my repro below. I hope it makes sense to you and that you'll be able to fix it.
