I have follow the guide to upgrade on tailwind https://tailwindcss.com/docs/upgrade-guide.
But I know get an error on my ionic angular app
TypeError: Cannot read property '700' of undefined
It seems that the version of the tailwind plugins I had was not compatible with Tailwind v3
I had to update theme, tailwind typography and forms in my case.
npm install -D @tailwindcss/typography@latest \
@tailwindcss/forms@latest
