Describe the bug When submitting a sceneEditUpdate mutation with a mismatched operation enum, GQL will pass through an internal system error

To Reproduce

1. Create an edit via WebUI with ID edit-uuid of enum CREATE
2. Update the edit via GQL query

mutation SceneEditUpdate {
    sceneEditUpdate(
        input: {
            edit: {
                comment: "edit"
                operation: MODIFY
            }
            details: { title: "lorem ipsum 2" }
        }
        id: "edit-uuid"
    ) {
        status
    }
}

response

{
    "errors": [
        {
            "message": "Internal system error. Error <runtime error: invalid memory address or nil pointer dereference>",
            "path": [
                "sceneEditUpdate"
            ]
        }
    ],
    "data": {
        "sceneEditUpdate": null
    }
}

Expected behavior An error explining that the operation ENUM does not match the targeted edit
