Root Cause

The request body contains a field that fails type validation, e.g., a string where an integer is expected.

generic

中文

请求体中的字段类型验证失败,例如在需要整数的地方提供了字符串。

Workarounds

  1. 95% success
    Ensure the client sends valid data types: age: 25 instead of age: "twenty-five".
  2. 85% success
    Add custom validation logic or use Pydantic's Field constraints to give better error messages.

Dead Ends

Common approaches that don't work:

  1. 80% fail

    It doesn't help the client correct the input; the error persists.

  2. 60% fail

    This bypasses validation and can lead to runtime errors when processing the data.
