## Description
Unable to build module-federation example for production.

I have been able to run the module-federation example on dev but I have been trying to change the implementation to an actual production level code. So I started to build production bundles for each of the modules.

I have been able to produce release bundles for **host** and **app2** MFs using the following command:

`STANDALONE=1 webpack -c webpack.config.mjs --env platform=ios --env mode=production`

But when trying to run the same command on **app1** and **module1** MFs, I am getting the following error:

```
[webpack-cli] TypeError [ERR_INVALID_ARG_TYPE]: The "path" argument must be of type string. Received undefined
```

## Reproducible Demo

```
git clone https://github.com/callstack/repack-examples
cd repack-examples
yarn run bootstrap
cd app1
npx STANDALONE=1 webpack -c webpack.config.mjs --env platform=ios --env mode=production
```

**Output**

```
[webpack-cli] TypeError [ERR_INVALID_ARG_TYPE]: The "path" argument must be of type string. Received undefined
