The article reports on a common error in Next.js App Router, "Text content does not match server-rendered HTML", which occurs when the server-generated HTML does not match the React tree built during the first browser rendering. This error is caused by non-deterministic content that varies between server and client rendering, often due to the use of Date(), Math.random(), localStorage, or browser APIs directly in the render.
To solve the issue, developers can follow four steps: remove non-deterministic logic from the render, disable iOS automatic detection, use suppressHydrationWarning as an escape hatch, and verify Edge/CDN configurations.
