How to debug `Cannot read properties of undefined (reading 'css')`?

Description

I am getting this error:

🐼 error [file:extract] TypeError: Cannot read properties of undefined (reading 'css')

I added console.log to _StyleEncoder.processAtomicRecipe and it shows:

{ compoundVariants: [] }
{ compoundVariants: [] }
{ compoundVariants: [ undefined, undefined ] }
🐼 error [file:extract] TypeError: Cannot read properties of undefined (reading 'css') ...
{ compoundVariants: [] }
{ compoundVariants: [] }

Where does it get those undefined values from?

I can fix this by simply patching panda CSS to check if value is set, e.g.

compoundVariants.forEach((compoundVariant) => {
  if (compoundVariant) {
    this.processAtomic(compoundVariant.css);
  }
});

However, feels like an issue upstream.

I'm guessing this is coming from an extracted value that contains some stuff not resolved, e.g not static enough for the extractor to understand

using the panda debug command could help you find the file causing this can you provide a minimal repro so that I can look into it ?
