LangChain - Output Parsers

Given this Langchain code snippet:

output_parser = JsonOutputParser(auto_fix=True)
raw_output = '{"name": "Alice", "age": 30'  # missing closing brace
fixed_output = output_parser.parse(raw_output)
print(fixed_output)

What will be printed?

A{'name': 'Alice', 'age': 30}

BSyntaxError due to malformed JSON

CNone

DOriginal string without changes

Step-by-Step Solution

Solution:

Step 1: Understand auto_fix=True effect
It tries to fix broken JSON like missing braces automatically.
Step 2: Analyze the raw output and parsing
The raw JSON is missing a closing brace, but auto-fix adds it and parses correctly.
Final Answer:
{'name': 'Alice', 'age': 30} -> Option A
Quick Check:
Auto-fix fixes broken JSON = {'name': 'Alice', 'age': 30} [OK]

Quick Trick: Auto-fix adds missing braces to parse JSON correctly [OK]

Common Mistakes:

Expecting a syntax error instead of fix
Thinking output is None or unchanged string
Confusing print output with raw string
