I have the same issue ! Did you find a solution for this now ?

[CoOlDud3]

I was able to make it work locally for now by setting the following in tailwindcss.config.js:

plugins: [import('preline/preline.js')],

And then running the next.js application without --turbopack.

This won't work on Vercel though.
