The page cannot be accessed after enabling webpack.optimize.ModuleConcatenationPlugin, production environment packaging

Open the webpack.optimize.ModuleConcatenationPlugin plug-in. The page cannot be accessed after the production environment is packaged. The error is as follows:

Uncaught TypeError: Cannot read property "call" of undefined
    at b (bootstrap a00833d57ef2cc119d45:54)
    at Object.0 (app.3671491e819e13d1c344.js:1)
    at b (bootstrap a00833d57ef2cc119d45:54)
    at window.webpackJsonp (bootstrap a00833d57ef2cc119d45:25)
    at app.3671491e819e13d1c344.js:1

searching for a solution to no avail.

the introduction page of the plug-in is implicit and not very clear: https://webpack.js.org/plugin.

I hope that the friends who have this experience and solve the problem smoothly can give us some advice!

Uh, no, try raising the sourcemap level, which indicates that you can't see where the error is. on line 54 of b, the non-function calls the call method is hard to understand.
