PackageJsonSynchronizer error when configuring symfony/ux-chartjs (>=v2.31.0)

[fabgg]

Hello,

I’m trying to install symfony/ux-chartjs. Just before that, I upgraded my project to Symfony 7.4.*.
The Symfony Flex bundle is in version v2.10.0, and ux-chartjs is in v2.31.0.

During the Composer installation, I get the following error:

Symfony operations: 1 recipe (10c8450d5f6cd321a351399032a77ff4)
  - Configuring symfony/ux-chartjs (>=v2.31.0): From auto-generated recipe

In PackageJsonSynchronizer.php line 107:
                                                      
  Trying to access array offset on value of type int  

To quickly move forward, I temporarily modified PackageJsonSynchronizer.php at line 107 to avoid the error.

It looks like the issue might be related to an unexpected value in the package.json handling within the ux-chartjs bundle.

// before
if ('@' !== $name[0] || !str_starts_with($version, 'file:'.$this->vendorDir.'/') || !str_contains($version, '/assets')) {
    continue;
}

// after
if ((is_array($name) && '@' !== $name[0]) || !str_starts_with($version, 'file:'.$this->vendorDir.'/') || !str_contains($version, '/assets')) {
    continue;
}

Please let me know if you need more details or a reproducible example.

Hi, that's weird, do you have the same issue with a previous version?

I expect $name to be a string, like "@hotwired/stimulus" from peerDependencies, so checking if it's an array is not the good solution.

I wasn't able to reproduce the issue with:

symfony new sf-app-flex-1074 --webapp
cd sf-app-flex-1074
rm importmap.php
npm init
symfony composer req symfony/ux-chartjs

The dependencies are nicely added to the package.json:

➜  sf-app-flex-1074 git:(main) ✗ cat package.json
{
  "name": "sf-app-flex-1074",
  "version": "1.0.0",
  "description": "",
  "main": "index.js",
  "directories": {
    "test": "tests"
  },
  "scripts": {
    "test": "echo \"Error: no test specified\" && exit 1"
  },
  "author": "",
  "license": "ISC",
  "devDependencies": {
    "@hotwired/stimulus": "^3.0.0",
    "@hotwired/turbo": "^7.1.0 || ^8.0",
    "@symfony/stimulus-bridge": "^3.2.0 || ^4.0.0",
    "@symfony/ux-chartjs": "file:vendor/symfony/ux-chartjs/assets",
    "@symfony/ux-turbo": "file:vendor/symfony/ux-turbo/assets",
    "chart.js": "^3.4.1 || ^4.0"
  }
}

Maybe do you have a package.json to share with us, or a repository? Thanks
