我正在学习How To GraphQL Node.js教程，我正在学习"使用Prisma Bindings连接服务器和数据库"部分。我认为我已经根据教程正确设置了所有内容，但当我试图在GraphQL Playground中执行后突变时，它会抛出以下错误：
{
"data": null,
"errors": [
{
"message": "Variable '$data' cannot be non input type 'LinkCreateInput!'. (line 1, column 18):nmutation ($data: LinkCreateInput!) {n ^",
"locations": [
{
"line": 2,
"column": 3
}
],
"path": [
"post"
]
}
]
}
我甚至不确定我应该得到什么，但当我进行"信息"查询时，我会从我的index.js文件中得到信息："数据"：{"信息"："这是黑客新闻克隆的API！获取Rigth Witcha，ima获取ya！！"}
所以，我知道信息查询正在工作。当我尝试执行Feed查询时，我在GraphQl操场上得到了这个错误：
{
"data": null,
"errors": [
{
"message": "Cannot query field 'links' on type 'Query'. (line 2, column 3):n links {n ^",
"locations": [
{
"line": 2,
"column": 3
}
],
"path": [
"feed"
]
}
]
}
因此，只有Info查询在工作，而其他查询则不断发回错误。我太失落了，我真的想在GRaohQL上获得更多的技能。当我转到我的Prisma客户端时，我无法访问我的服务。他们只允许我查看服务器列表。我有控制台的截图，但我没有足够的声誉来发布这个问题。
我已经尝试过每一步，并确保我的代码是正确的。我也检查了HowToGraphql git存储库，但他们只有完整的服务器代码，我想从头开始构建我的代码，所以他们的代码没有多大帮助。我不确定问题是Prisma客户端还是我的代码。如有任何反馈或帮助，我们将不胜感激！！

请帮忙！！

更新
当我运行Prisma Deploy时，我可以收到一条错误消息：

数据模型中似乎有一个拼写错误，应该是@unique而不是@ unique。
