LangChain - Output Parsers

You wrote this code:

parser = JsonOutputParser()
result = parser.parse({'name': 'Bob'})

What is the problem here?

AThe parser instance must be initialized with arguments

BNo problem, it works correctly

CJsonOutputParser cannot parse dictionaries with strings

Dparse expects a JSON string, not a Python dict

Step-by-Step Solution

Solution:

Step 1: Check input type for parse()
parse() expects a JSON formatted string, but a Python dict was passed.
Step 2: Identify the error cause
Passing a dict instead of a JSON string will cause a type error or failure because the parser cannot parse Python objects directly.
Final Answer:
parse expects a JSON string, not a Python dict -> Option D
Quick Check:
parse input must be JSON string [OK]

Quick Trick: Always pass JSON strings, not Python dicts, to parse() [OK]

Common Mistakes:

Passing Python dicts directly to parse()
Assuming parse auto-converts dicts
Thinking parser needs arguments on init
