Solution: TypeError: Cannot read properties of undefined (reading '700')

Low Risk

I specifically had the problem using nuxt/tailwindcss-module with `"@tailwindcss/typography": "^0.5.0",` , which seems to not be compatible anymore with tailwindcss < 3.0.0. The Nuxt TailwindCSS module uses tailwind:"^2.0.4" and is not upgraded yet to Tailwind 3, see https://github.com/nuxt-community/tailwindcss-module/pull/407 Downgrading to `"@tailwindcss/typography": "^0.4.1",` works for me!
