GraphQL filter not working as intended

[JelmerOT]

Bug description

I made a query to fetch articles based on the ID of the taxonomy.

query MyQuery {
  entries(
    collection: "articles"
    site: "nl_nl"
    filter: {
      article_categories: {
        id: { is: "article_categories::slapen" }
      }
    }
  ) {
    from
    to
    data {
      id
      url
      date
      title
      status
      permalink
      ... on Entry_Articles_Article {
        id
        article_categories {
          id
          title
          url
          slug
          uri
        }
      }
    }
  }
}

This is what it returns:

{

    "entries": {
      "from": 1,
      "to": 2,
      "data": [

              "uri": "/blog/article-categories/droomsap"
            },
            {

              "title": "Onderzoek",
              "url": "/blog/article-categories/onderzoek",
              "slug": "onderzoek",
              "uri": "/blog/article-categories/onderzoek"
            }
          ]
        },
        {
          "id": "35b520ab-e84e-47d5-99e5-c957a23d20b3",
          "url": "/blog/het-slopende-effect-van-insomnia",
          "date": "2024-06-11 00:00:00",

          "status": "published",
          "permalink": "http://localhost:3000/blog/het-slopende-effect-van-insomnia",
          "article_categories": [
            {
              "id": "article_categories::droomsap",
              "title": "Droomsap",
              "url": "/blog/article-categories/droomsap",
              "slug": "droomsap",
              "uri": "/blog/article-categories/droomsap"
            },
            {
              "id": "article_categories::onderzoek",
              "title": "Onderzoek",
              "url": "/blog/article-categories/onderzoek",
              "slug": "onderzoek",
              "uri": "/blog/article-categories/onderzoek"
            }
          ]
        }
      ]
    }
  }
}

You can see that the second article does not contain a taxonomy with an id of article_categories::slapen.

How to reproduce

Create a new statamic project. Create an articles collection and article_categories taxonomy. Connect these two.

Then query the articles with a filter.

You can filter entries by taxonomies like this:

query MyQuery {
  entries(
    collection: "articles"
    filter: {article_categories: {contains: "slapen"}}
  ) {
    data {
      id
      title
    }
  }
}

That works, but not with another category with a similar name. Seems that contains just looks if the word exists somewhere.

And I can't do something like this, because I get an error:

filter: {
  article_categories: {
    is: "slapen"
  }
}

The error:

strtolower(): Argument #1 ($string) must be of type string, array given

Ah, yeah. I was just referencing the answer to a previous discussion: #4983
