Root Cause

Object literal does not satisfy the required properties of the target type.

generic

Workarounds

  1. 97% success Add the missing required properties to the object literal 
    Provide values for all required fields of the type
  2. 85% success Use Partial<T> only if the function truly accepts partial objects, and update consumers accordingly 
    Partial<T> makes all properties optional — only use when intentional

Dead Ends

Common approaches that don't work:

  1. Making all properties optional with Partial<T> 70% fail

    Changes the contract; callers may pass incomplete objects

  2. Using type assertion: {} as T 85% fail

    Compiles but fails at runtime when properties are accessed
