[5.7.6]: GraphQL query on an entry with a Matrix field returns duplicates of the actual Matrix blocks

[MartinSchmid2409]

What happened?

Description

Below is an actual working query. The problem is the field "lookoutArticle" which is a Matrix field. The actual entry has 5 content blocks inside the matrix field. But the GraphQL query returns lots of duplicates of each of these 5 content blocks (I checked it: same id). I´ve tried all and everything to get rid of these duplicates, but no chance. Google and ChatGPT also did not help. Did I oversee something? I just want to return the entry as it is shown in the Craft CMS admin backend. I want to see a GraphQL response with 5 entries inside the Matrix block (and not ~35).

Steps to reproduce

REQUEST:

query GetLookoutEntry {
  entry(site: "bbm_de", section: "lookout", status: "live", trashed: false, slug: "test-de") {
    slug
    ... on lookoutEntry_Entry {
      lookoutSeoTitle
      lookoutSeoMetaDescription
      lookoutHeadline
      lookoutTeaserLong
      lookoutImageMain {
        id
        url(transform: "lookoutTransformArticle")
      }
      lookoutArticle(site: "bbm_de", status: "live", trashed: false) {
        __typename
        ... on lookoutBlockText_Entry {
          lookoutBlockText {
             __typename
          }
        }
        ... on lookoutBlockImage_Entry {
          lookoutBlockImage {
            id
            siteId
          }
        }
        ... on lookoutBlockEmbeddedAsset_Entry {
          lookoutBlockEmbeddedAsset {
            id
            siteId
          }
        }
      }
    }
  }
}

Expected behavior

GraphQL response: Matrix field entries not duplicated lots of times.

Actual behavior

GraphQL response: Matrix field entries ARE duplicated lots of times.

Okay, I have solved this, and I think it is a bug. Or at least unintentional or unwanted behavior.

This is caused because of Versioning introduced for Matrix fields as of Craft 5.7:
https://craftcms.com/docs/5.x/reference/field-types/matrix.html#versioning

When I disabled "Enable versioning for entries in this field" on field "lookoutArticle" I didn´t get duplicates anymore from GraphQL response. But onyl for new entries created after altering this setting.

So, GraphQL as a default, returns all versions of the entries of a Matrix field. This behavior cannot be intentional. From a practical view, it does not make any sense.

Desired behavior: GraphQL should only return the latest versions of the entries of a Matrix field no matter if "Enable versioning for entries in this field" is enabled or not.

Additional question: Is there any query argument I can add to the GraphQL to omit having versioned Matrix field entries in the response? If no, there should be one, at least ;)

@MartinSchmid2409
I had the same as you, what was weird is that if you uncheck the versioning, the data remains duplicated.
So there might be a bug.

Hi, thanks for getting in touch and for all the info.

Is there any query argument I can add to the GraphQL to omit having versioned Matrix field entries in the response?

You can add revisions: false to your lookoutArticle query to exclude revisions.

I’m looking into this and will update this issue once I have more info.

[i-just]

I raised a PR to improve this.

Craft 5.7.8 is out with that fix. Thanks again!
