DevTools failed to load SourceMap: Could not load content

What it means here is that the dev tool failed to load the source mapping: it couldn’t load the content. The focus is on the part after the for.
The hint I encountered was something like this

DevTools failed to load SourceMap: Could not load content for chrome extension://ncennffkjdiamlpmcbajkmaiiiddgioo/js/xl-content.js.map

That is, the part of the chrome extension tool, the mapping failed to load successfully.

After inquiry, the latter link is caused by the opening of the Xunlei extension tool in chrome, but it does not affect normal operation, you can also consider disabling the tool in the extension program
