Root Cause

Passing a Python object that cannot be converted to a database-compatible type (e.g., a custom class instance without proper type adaptation).

generic

中文

传递了一个无法转换为数据库兼容类型的 Python 对象（例如，没有适当类型适配的自定义类实例）。

Workarounds

  1. 90% success Convert to supported type 
    Convert the value to a supported type like int, float, str, or datetime before passing to the query.
  2. 80% success Register custom adapter 
    Register a custom type adapter using sqlite3.register_adapter() for custom classes.

Dead Ends

Common approaches that don't work:

  1. Converting to string blindly 50% fail

  2. Retrying without type fix 90% fail
