title: What prompts chrome devtools to look for source maps
body: <p>I am getting warnings like <code>DevTools failed to load SourceMap: Could not parse content for http://localhost:8000/index.js.map: Unexpected token &lt; in JSON at position 0</code> where chrome is trying to a fetch a source map that doesn't exist. Why has chrome decided there should be a source map in this case and how can I prevent it from doing so?</p>
