Multiple medias not showing in my API

Questions and Answers Database-SQL

Hello,
I’m creating a portfolio with Strapi. I have “project” collection type including :

  • slug (UID)
  • title (Text)
  • description (Rich text)
  • thumbnail (single media)
  • gallery (multiple media)
  • categories (relation with another collection: “category”)

When I open my API http://localhost:1337/api/projects?populate=* here is what I got :

{
    "data": [
        {
            "id": 1,
            "attributes": {
                "slug": "title",
                "title": "Title",
                "description": "Text",
                "createdAt": "2022-06-13T15:58:12.851Z",
                "updatedAt": "2022-06-15T10:52:08.092Z",
                "publishedAt": "2022-06-13T15:58:16.392Z",
                "thumbnail": {
                    "data": {
                        "id": 1,
                        "attributes": {},
                        }
                    }
                },
                "categories": {
                    "data": [
                        {
                            "id": 1,
                            "attributes": { ... }
                        },
                        {
                            "id": 3,
                            "attributes": { ... }
                        }
                    ]
                }
            }
        }
    ]
}

As you may notice, every field is showing well except of my gallery one (multiple media).
Can someone help me?

Thanks!
