**Root Cause Analysis:** The `json` module is not imported in main.py, but the `format_greeting` function attempts to use `json.dumps()` on line 17, resulting in a NameError. **Fix Applied:** Add missing json module import to main.py **Reasoning:** The error is a classic Python NameError indicating that the `json` identifier is not defined in the current scope. The code uses `json.dumps()` but never imports the json module. Adding `import json` at the top of the file will resolve this issue. The datetime module is already imported, so we just need to add the json import alongside it. **Confidence:** 0.99 **Model Used:** claude-sonnet-4-5-20250929 --- Fix ID: 19879512246 Attempt: 1

Problem
The application was failing at runtime due to a missing
jsonimport. Theformat_greeting()function attempted to usejson.dumps()without importing thejsonmodule, causing aNameError.Solution
Added the missing
import jsonstatement at the top of the file alongside the existingdatetimeimport. Additionally improved code clarity by:age,greeting) for better readabilityWhy It Works
The
jsonmodule is now properly imported before being used, resolving the runtime error. The code follows Python best practices by declaring all imports at the module level, ensuring thejson.dumps()call has access to the required functionality.
