我正在创建一个dribble克隆，在那里我使用grafbase查询我的数据，但它在生产上生成错误，它说“类别无效类型”null“预期为“字符串”，但我查询它的方式，它应该允许null，它在开发方面工作良好，但在生产方面它变得更加严格，我不知道如何解决这个问题。
以下是我的查询：

export const projectsQuery = `
  query getProjects($category: String , $endcursor: String) {
    projectSearch(first: 8, after: $endcursor, filter: {category: {eq: $category}}) {
      pageInfo {
        hasNextPage
        hasPreviousPage
        startCursor
        endCursor
      }
      edges {
        node {
          title
          githubUrl
          description
          liveSiteUrl
          id
          image
          category
          createdBy {
            id
            email
            name
            avatarUrl
          }
        }
      }
    }
  }
`;

字符串
这是我通过查询访问数据的代码：

export const fetchAllProjects = (
  category?: string | null,
  endcursor?: string | null
) => {
  client.setHeader("x-api-key", apiKey);

  return makeGraphQLRequest(projectsQuery, {
    category,
    endcursor,
  });
};

我尝试了许多其他的方法通过chatgpt & docs，但似乎没有工作，我是新手在grafbase，请让我知道如果你有信息.阅读更多
