"Failed to load extension from .../build. Could not load javascript 'static/js/0.chunk.js' for content script.

[xush6528]

I get a pop up error message box from chrome on reloading my extension.

This is my manifest.json, https://gist.github.com/xush6528/b2721f54f34fc740e4e2facdd44cb800

I wonder what other requirements this solution has.

My hypothesis is that the building has not finished yet, the extension reloading is fired, thus resulting chrome to load broken files.

Yeah, could be the case. I guess a white-list of watched files could help, so that the extension would reload only when a specific file is updated. A larger timeout could also help.
