Hey,
having trouble with upgrading from next 12.3.4 --> 14.2.4 (tried different minor/patch releases) that assets via /_next/static no longer use the headers defined in next.config.js around CORS headers. I'm serving certain "public" folder and next.js generated assets via different subdomain via assetsUri so CORS headers are important for it . Went trough all release logs and docs and don't see any mentions about this regression.
So I'm not sure if expected or a bug?
