A JSON-related error in a Multi-Agent Supervisor setup in LangGraph typically arises from improper serialization or incorrect data structure formatting. This can be resolved by ensuring that a JSON-compatible message is passed.
Here is the code snippet you can refer to:

In the above code we are using the following key points:
- Defines a Multi-Agent Supervisor using LangGraph's Agent class.
- Implements JSON Parsing with Error Handling to avoid format issues.
- Uses a Graph Structure to connect the agent and manage execution.
- Ensures JSON-Compatible Message Passing to prevent decoding errors.
- Validates Input Before Processing to catch malformed JSON early.
Hence, properly formatting JSON messages and handling decoding errors ensures smooth communication in a Multi-Agent Supervisor setup within LangGraph.
