根因分析

客户端发送的 GraphQL 查询或变更中使用了错误类型的参数值（例如字符串而非整数）。

English

The client sent a GraphQL query or mutation with an argument value of the wrong type (e.g., string instead of integer).

解决方案

  1. Ensure the client sends the correct type: for integers, avoid quoting (e.g., `{ "query": "query { items(limit: 10) { id } }" }`).
  2. Use a variable with a proper type definition: `query($limit: Int!) { items(limit: $limit) { id } }` and pass `{"limit": 10}` in the variables.

无效尝试

常见但无效的做法:

  1. 90% 失败

    GraphQL strict typing rejects mismatched types unless coercion is explicitly defined.

  2. 60% 失败

    Clients unaware of the custom scalar may still send strings.
