Getting a very similar error with a nearly clean Next 15 project.

Hey! We'd love to investigate this but the shared codesandbox does not reproduce the issue, can you share a reproduction?

I.e. when running your sandbox it works: https://codesandbox.io/p/devbox/hardcore-fermat-z4fttc?file=%2Fapp%2Fpage.tsx&workspaceId=062b139a-c054-40fe-bbf5-0210d48b9dd0

Hello, I had exact same error when trying to run latest stable NextJS15 with tailwind. In my case the issue was related with the content config in tailwind.config.ts where one line was causing this fatal error:

export const content = [
    "./app/**/*.{js,ts,jsx,tsx,mdx}",
    "./pages/**/*.{js,ts,jsx,tsx,mdx}",
    "./components/**/*.{js,ts,jsx,tsx,mdx}",

    // The line below causes fatal error in turbo mode
    "./src/app/[locale]/**/*.{js,ts,jsx,tsx}",
];

Once I removed [locale] part from this content config, it built fine with turbo. Maybe it'll help some of you.

I ran into this as well using and narrowed it down to an intercepted route on a dynamic param, i.e. (.)[dynamicParam] in case it's helpful to anyone

Any updates on this? I ran into the same error when an intercepted route with dynamic param is defined -> (.)[id]

[UPDATE]

I solved the problem by avoiding creating folders with parentheses followed by brackets and navigating back using double dots. Going from this:

photo-feed/
├─ @modal/
│  ├─ (.)[id]/
│  │  └─ page.tsx
│  └─ default.tsx
├─ [id]/
│  └─ page.tsx
├─ layout.tsx
└─ page.tsx

to this:

photo-feed/
├─ @modal/
│  ├─ (..)photo-feed/
│  │  └─ [id]/
│  │     └─ page.tsx
│  └─ default.tsx
├─ [id]/
│  └─ page.tsx
├─ layout.tsx
└─ page.tsx

Seeing this in our monorepo too

doesn't seem to be tailwind related, we do have a couple of intercept routes, too many to change, same panic

I get the same "glob char" error after upgrading to tailwind v4 with npx @tailwindcss/upgrade@next.

I get the same "glob char" error after upgrading to tailwind v4 with npx @tailwindcss/upgrade@next.

We actually upgraded recently to tailwind v4 as well

So basically it works if we remove all the route intercepts, @ijjk

Pretty sure this should be an easy fix

I ran into this issue when upgrading to tailwind 4.

I can reproduce a more minimal version here.
Here were the steps used to create this repro:

1. npx create-next-app@latest with default options but no to tailwindcss.
2. Follow tailwind v3 installation guide https://v3.tailwindcss.com/docs/guides/nextjs (steps 2-6)
3. Update to v4 with @tailwindcss/upgrade@next
4. In the app directory, create @test/(.)[test]/page.tsx and put a react component in it.
5. Run the server npm run dev and open it in browser.
6. This issue occurs.

I'm not sure if this is the most minimal reproduction that is possible, but is the closest match to my current situation.

@SebassNoob I was able to fix this by installing the @tailwindcss/postcss package in my project.

really? I'm still getting the glob char sequences are not implemented yet error.

Same issue - when Upgrading to tailwind. We also use intercepted route, changing it to (..) did not work. However removing the route / folder.
Building is not affected, removing turbo flag from dev also makes "fixes" it.
