Root Cause

An output value's declared type does not match the actual type of the expression result.

generic

中文

输出值的声明类型与表达式结果的实际类型不匹配。

Workarounds

  1. 95% success Correct the type declaration to match the expression: e.g., change type = string to type = list(string) if output is a list 
    Correct the type declaration to match the expression: e.g., change type = string to type = list(string) if output is a list
  2. 85% success Use tostring(), tolist(), etc. to convert the value to the declared type 
    Use tostring(), tolist(), etc. to convert the value to the declared type

中文步骤

  1. 修正类型声明以匹配表达式：例如，如果输出是列表，将 type = string 改为 type = list(string)
  2. 使用 tostring()、tolist() 等函数将值转换为声明的类型

Dead Ends

Common approaches that don't work:

  1. 50% fail

    Without type constraint, output may still fail if used elsewhere expecting a specific type.

  2. 70% fail

    Hides the type mismatch but may cause downstream failures.
