Symfony version(s) affected

7.3

Description

While working on symfony/ai#136 I found a behavior I'm not quite certain if intended or not.

With a JSON like this:

{
  "choices": [
    {
      "message": {
        "content": null
      }
    }
  ]
}

(Extended file)

And a JsonPath like this: $.choices[?length(@.message.content) >= 0].message.content

I get an array with null [0 => null], but would just expect [] as result.

How to reproduce

To add in JsonCrawlerTest:

    public function testEmptyLengthFunction()
    {
        $crawler = new JsonCrawler('{"choices": [{"message": {"content": null}}]}');
        $result = $crawler->find('$.choices[?length(@.message.content) >= 0].message.content');

        $this->assertSame([], $result);
    }

See chr-hertel#1

Possible Solution

I'm open for fixing this, but would need some serious pointers.
