Building a Next.js app with @kinde-oss/kinde-auth-nextjs failed with Cannot find module 'next/headers' imported from the Kinde auth package. The SDK imported next/headers in a context where Next did not provide it, breaking the build. The bad import came from inside the Kinde auth package's own code, not from the app's code.

Fixed in @kinde-oss/kinde-auth-nextjs 2.5.4; upgrade to 2.5.4 or newer and the build succeeds. The reporter confirmed the latest version resolved it. No app-side changes were needed; the fix was entirely in the SDK's imports. Source: https://github.com/kinde-oss/kinde-auth-nextjs/issues/305
