# webpack-resolver-cache-plugin-bug-repro

Reproduces a potential bug in v5.69.0 of webpack.

First, install dependencies:

```

yarn install

```

Next, copy reduced version of internal company modules into the `node_modules` directory:

```

cp -r company_node_modules/@company node_modules

```

Finally, build the project:

```

yarn build

```

Observe the following error:

```

/webpack-resolver-cache-plugin-bug-repro/node_modules/webpack/lib/cache/ResolverCachePlugin.js:248

													if (result) for (const r of result) yield_(r);

													                            ^

TypeError: result is not iterable

```

Note that if you run `yarn build` after removing `resolve.plugins` from `webpack.config.js`, you will not see an error, but you will see a warnings, which is the expected behavior:

```

WARNING in ./node_modules/@company/react-accessibility/dist/useId.browser.js 2:22-39
