@dylan-chong Did you figured out how to solve this error ?

[dylan-chong]

Nope

I'm having this same issue.

[stephanschubert]

Same here with webpack v4.14.0.

Same problem.

FYI, this happened to me when trying to use HtmlWebpackPlugin for my webpack config during testing. Removing the plugin fixed the issue.

[soeik]

Same problem with DojoWebpackPlugin. But I can't remove it. :(

[snowyu]

Me too for using HtmlWebpackPlugin.

Anyone had success with HtmlWebpackPlugin and Jest?
