`nx report` results in "Failed to process project graph. Run "nx reset" to fix this" about nx HOT 5 CLOSED

It also happens after installing a second app.

After I do a successful: "nx g @nx/react:app website" all is fine

But then when I try to add another app: "nx g @nx/express:app api" then I see this error:

"NX Failed to process project graph. Run "nx reset" to fix this. Please report the issue if you keep seeing it."

This is a blocker and should be treated as urgent. It's impossible to use NX at this point to create a functional application.

Let me take a closer look at what is causing the plugin graph to fail during creation and I'll update here again

Hey @beeman !

So it's a true error, it's just a little bit hidden unfortunately.

The error comes from the web/webpack.config.js file.

It's trying to set fallback on config.resolve when resolve is undefined

console.log("config.resolve", config.resolve);
  config.resolve.fallback = {
    crypto: require.resolve('crypto-browserify'),
    stream: require.resolve('stream-browserify'),
  };

output:

config.resolve undefined

Changing that section to:

config.resolve ??= {};
  config.resolve.fallback = {
    crypto: require.resolve('crypto-browserify'),
    stream: require.resolve('stream-browserify'),
  };

Allows it to work:

To uncover errors like these, you can run NX_DAEMON=false pnpm nx graph
Or you can check in the .nx/cache/d/daemon.log

Thanks for checking this @Coly010 .

I don't think this should be closed, as it's a regression.

The same webpack.config.js worked fine in previous versions. For example in this repo there is the exact same file, and pnpm nx report works as expected.

The previous and expected behavior is that these webpack options are merged. With that in mind, it only makes sense that it would create any missing parent keys.

This is very useful, thanks. I've been getting these errors all the time lately and never knew how to debug it!

Hi @beeman :)

The repo you linked in the latest comment doesn't using Inference Plugins, therefore the webpack.config.js files are not being resolved.

If you set the webpack plugin in the pubkey repo, and run nx reset and then nx report, you'll see it also fails.

Therefore, I would not say this is a regression.

When resolving the webpack config, which in this case returns a function which takes a config object and transforms it, we pass an empty object as the starting point for the config, which is then built up over time.

There are some config options that are only set during the actual build when using withNx. Perhaps we can initialize some more with empty objects.
