did you mean disable Source Maps / uncheck ? i have enable that.

Uncheck it and that should remove the errors.
It seems like an upstream error like @elken mentioned https://github.com/webpack/webpack/issues/1194
I'm closing this one as there isn't much we can do about it :cry:. There is no easy upstream fix we can do. @qipoy it's a warning so it shouldn't break your site anyway so you can just clear it. Sorry for the inconvenience.
