Laravel Lighthouse GraphQL array to string error

Why is it that in the Lighthouse Docs, upload directive is listed and explained, but trying to use it in the schema:

scalar Upload @scalar(class: "Nuwave\\Lighthouse\\Schema\\Types\\Scalars\\Upload")


extend type Mutation {
    createImageList(
        id: ID!
        category_id: String!
        image_path: [Upload!]! @upload(disk: "public", path: "images/gallery", public: true)
        thumbnail: String!
        label: String
        description: String
        tags: JSON
        favorite_count: Int
    ): GalleryImageList @upsert
}

returns:

"debugMessage": "No directive found for upload"

I later checked the changelog of Lighthouse, and found out that upload directive was added in v5.6. Using composer require nuwave/lighthouse added v5.58 of Lighthouse instead, which is an unexpected behavior.

I finally used: composer require nuwave/lighthouse dev-master Which updated Lighthouse to the latest version v5.68+

Now, I got a new error:

"debugMessage": "Array to string conversion",
            "message": "Internal server error"

I hope to find a way to upload files using upload directive soon.

Solution

  • ==== SOLVED ==== Added json cast to image_path field, and wolla, it worked! It returned the following, with the 3 images uploaded, and the generated file names saved to database. ["images\/gallery\/LimSUx2xO9yvLYZg0Pl8L05MRcFISnLTprx1hOUq.jpg","images\/gallery\/3k8NSpOJFu6oYxplMW7Bik2j12mmVsHcOK1ZM4qJ.jpg","images\/gallery\/lRnpeAquOItYPZ35jPL2rBBDojWdxM2JkKosJ7Su.jpg"]

    I am still testing the url of the uploaded image on the api:

    localhost/images/gallery/LimSUx2xO9yvLYZg0Pl8L05MRcFISnLTprx1hOUq.jpg

    Returns: 404 Not Found
