Nest/Pnpm cannot create isolated production bundles with generatePackageJson: true and externalDependencies: none

[rudfoss]

Current Behavior

Building a Nest application with generatePackageJson: true in webpack.config.js produces a partial package.json file as output from a clean nx workspace missing the tslib dependency. From what I can read from the source code for the plugin the file webpack/src/plugins/generate-package-json-plugin.ts should in fact add the necessary external dependencies to the configuration, but debugging through it locally it fails to read the tsconfig file.

Using pnpm install --frozen-lockfile on the produced package.json file also fails because the pnpm-lock.yaml is also incomplete. I've worked around the issue by replacing the lockfile with my complete lockfile for the entire workspace, but that is not ideal.

In an attempt to avoid any bundling issues I've also tried to set externalDependencies: "none" in webpack.config.js which the documentation says is the default anyway, but that breaks both the build and serve targets due to failures when resolving modules.

Expected Behavior

Setting generatePackageJson: true should produce a complete package.json file with a valid pnpm-lock.yaml file.
Using externalDependencies: "none" should produce a single-file bundle without the need for installing modules at all if I understand things correctly.

Steps to Reproduce

Reproduction repository provided with additional log details.

1. Create a new nx workspace
2. Install nest plugin
3. Generate nest application
4. Modify webpack.config.js by setting generatePackageJson: true and externalDependencies: "none".
5. Try to build or serve the application.

Failure Logs

Installing using --frozen-lockfile:
pnpm i --frozen-lockfile
Lockfile is up to date, resolution step is skipped
 ERR_PNPM_LOCKFILE_MISSING_DEPENDENCY  Broken lockfile: no entry for '/iterare/1.2.1' in pnpm-lock.yaml

This issue is probably caused by a badly resolved merge conflict.
To fix the lockfile, run 'pnpm install --no-frozen-lockfile'.
