In React, a hydration error is when the server-side rendered DOM doesn’t match the client-side rendered DOM. There are several reasons why this can happen so it’s difficult to troubleshoot without seeing the whole error and stack trace. A common reason is invalid markup, but not the only reason. What more can you share about the error you are seeing?
