Next.js: How to debug warning: Expected server HTML to contain a matching <a> in <div>

Created on 8 Oct 2019 · 1Comment · Source: vercel/next.js

Question about Next.js

I am using Semantic-UI React and Next.JS but it appears at breakpoint < 768px, my layout completely breaks upon a refresh of the browser. I know because its a react/next.js app they are taking care of the routing but I guess I wondered what if a user happen to do that?

It doesn't happen on my /login, /register or /profile routes

What is strange is I've checked my files in pages/ directory and don't see any unmatched <a> tags in a </div>

This is the Semantic-UI-component which contains the error:

import PropTypes from 'prop-types'
import React, { Component } from 'react'
import {
 Button,
 Container,
 Divider,
 Grid,
 Header,
 Icon,
 Image,
 List,
 Menu,
 Responsive,
 Segment,
 Sidebar,
 Visibility,
} from 'semantic-ui-react'

// Heads up!
// We using React Static to prerender our docs with server side rendering, this is a quite simple solution.
// For more advanced usage please check Responsive docs under the "Usage" section.
