Cannot read property 'push' of undefined

[aladdin-add]

it was working in [email protected], but seems not working with the latest webpack and the plugin:

webpack: 5.0.0.beta.23 node.js: v14.5.0 webpack-fast-refresh: 5.0.4 react-refresh: 0.8.3

I've created a simple repro: https://github.com/aladdin-add/issue7 (it was simplified from a private repo)

thanks in advance!

having the same issue, as soon as you place ReactRefreshPlugin(), on plugins you get that error, last known setup is with webpack 5.0.0-beta.22 + webpack-fast-refresh 5.0.1

Something's going on with html-webpack-plugin. I've never used it before but looking into it.

In the meantime, I strongly suggest switching to https://github.com/pmmmwh/react-refresh-webpack-plugin

It is the "official" react refresh plugin and it looks to be working with html-webpack-plugin without issues. It also now has full support for webpack v5.

The same for me after I've upgraded to webpack 5.0.0-beta.29
