How to fix "2200M: invalid_xml_document" in PostgreSQL
PostgreSQL throws 2200M (invalid_xml_document) when libxml2 rejects the payload passed to XMLPARSE, XMLTABLE, XML functions, or an xml column insert because the text is not a well-formed XML document. The parser wants a single root node and complete tag structure, so missing roots, stray text nodes, or bad syntax cause the query to fail before the server ever stores or evaluates the value.

How to fix "Unexpected 0 Rendered in JSX" in React

How to fix "PureComponent shallow comparison not working correctly" in React
React PureComponent shallow comparison fails when props or state contain objects and arrays that are mutated in place instead of recreated with new references. PureComponent uses shallow equality checks, comparing primitives by value but objects and arrays by reference only. When complex data structures are mutated without creating new references, PureComponent won't detect changes and components won't re-render. The fix involves creating new object/array instances, avoiding inline function creation, and understanding when to use memo or custom shouldComponentUpdate instead.
