next dev mode not working with next 12.0.3, antd 4.16.13

Hi! I'm using the latest versions of next (12.0.3), antd (4.16.13) and next-with-less (2.0.2). Things were working fine until next 12.0.2. However, something broke with 12.0.3. Production mode (next build && next start) works fine, but dev mode (next) doesn't. This is the error I'm getting:

error - ./node_modules/antd/dist/antd.less:4:0

I'm reporting this here because, since next doesn't support less, I don't think they're gonna regard this as their issue 😓

It's a bug within Next.js. Should be fixed in 12.0.4. You can wait for that, or stick to 12.0.2 for now. Or try next@canary as it should be fixed there.

Awesome, thanks for that quick reply @chemicalkosek . I'll leave this open until next 12.0.4 is released and I can confirm that it indeed solves this problem.

We can safely close it now since the bug has been fixed in next 12.0.4.
