Root Cause

A field typed as an Enum receives a value not defined in the enumeration.

generic

中文

类型为枚举的字段接收到未在枚举中定义的值。

Workarounds

  1. 95% success 
    Use enum member: Color.RED
  2. 90% success 
    Add custom validator to map strings to enum

Dead Ends

Common approaches that don't work:

  1. 80% fail

    Enum member type mismatch.

  2. 70% fail

    Pydantic expects the value, not name.
