Additional context

I'd like to create UI similar to Github weed, so I tried Cal-Heatmap library in side project.
I use to next dev --turbo by default so I encountered this issue.

I'm glad to this report will help Turbopack get a little closer to Webpack's drop in replacement. 😄

The import unfortunately is too dynamic for turbopack to analyze, I'm not sure if this is something that can be fixed soon.

@ForsakenHarmony Thanks for your hard work on this project! I noticed that the import is too dynamic for Turbopack to analyze. Hope this can be resolved. Keep up the great work!

@sokra mentioned we'll likely have to support the .concat case as webpack analyzes it too

[ForsakenHarmony]

Will be fixed with the next canary after turbopack is updated
