突变在 GraphQL 浏览器上工作，但从 nuxt 前端发送时不起作用

Question

我有这个 GraphQL：

mutation MyMutation($dayPhone: String!, $email: String!, $firstName: String!, $noOfDoors: String!, $noOfFrenchPatio: String!, $noOfWindows: String!, $postcode: String!, $quotationDate: DateTime!, $quotationId: String!, $refCode: String!, $surname: String!, $slug: String!, $authorId: ID!) {
  save_quotes_quotation_Entry(
    dayPhone: $dayPhone
    email: $email
    firstName: $firstName
    noOfDoors: $noOfDoors
    noOfFrenchPatio: $noOfFrenchPatio
    noOfWindows: $noOfWindows
    postcode: $postcode
    quotationDate: $quotationDate
    quotationId: $quotationId
    refCode: $refCode
    surname: $surname
    slug: $slug
    authorId: $authorId
  ) {
    id
  }
}

当在我的 Craft CMS 内的 GraphQL 资源管理器中执行时，它完美运行，创建了一个引用条目，当从我的 nuxt3 前端执行时，我收到以下错误：

{
    "errors": [
        {
            "message": "Cannot query field \"save_quotes_quotation_Entry\" on type \"Mutation\".",
            "extensions": {
                "category": "graphql"
            },
            "locations": [
                {
                    "line": 16,
                    "column": 3
                }
            ]
        }
    ]
}

为什么会这样，两者都使用完全相同的语法。
