"@parcel/packager-css: Unsupported layer combination in @import"

[Offirmo]

🙋 feature request

The great Parcel bundler is now supporting CSS layers! However it's throwing an error at my face: "@parcel/packager-css: Unsupported layer combination in @import"

I trust Parcel and I'm sure I did something wrong. However the error message is not helpful and despite carefully reviewing all my CSS, I can't find the issue at all. Could the error message log what CSS line causes the issue?

🤔 Expected Behavior

The error message would be accompanied by some sort of stack trace.

😯 Current Behavior

🚨 Build failed.

@parcel/packager-css: Unsupported layer combination in @import

  SyntaxError: Unsupported layer combination in @import

No stack trace, I can't find what causes the error.

💁 Possible Solution

How about printing the @import ... line that is causing an issue? Or any kind of stack trace.
