Original Pull Request: https://github.com/langgenius/dify/pull/24329

State: closed
Merged: Yes

Fixes: #24328

This PR corrects a misleading exception reference related to Python’s json module.
json.dumps() was previously described as potentially raising json.JSONDecodeError, which is not possible.

json.dumps()

  • Purpose: serialize a Python object into a JSON string.
  • Possible error: TypeError when the object is not JSON-serializable (e.g., contains set, bytes, or unsupported custom objects).
  • It does not raise json.JSONDecodeError.

json.loads()

  • Purpose: deserialize a JSON string into a Python object.
  • Possible error: json.JSONDecodeError when the input string is not valid JSON.
