Bug Report

Description

When using the OpenAI Agents SDK with file search or web search tools, on_span_end raises:

ERROR:openai.agents:Error in trace processor <agentops.instrumentation.agentic.openai_agents.processor.OpenAIAgentsProcessor
object> during on_span_end: 'NoneType' object has no attribute 'dict'

Root Cause

In agentops/instrumentation/providers/openai/attributes/response.py, three hasattr() checks guard calls to .__dict__ on
optional tool fields — but hasattr() returns True even when the attribute value is None:

get_response_tool_web_search_attributes (line ~507):

if hasattr(tool, "user_location"):
    parameters["user_location"] = tool.user_location.__dict__  # crashes if None

get_response_tool_file_search_attributes (lines ~525, ~531):
if hasattr(tool, "filters"):
    parameters["filters"] = tool.filters.__dict__  # crashes if None

if hasattr(tool, "ranking_options"):
    parameters["ranking_options"] = tool.ranking_options.__dict__  # crashes if None

user_location, filters, and ranking_options are all optional fields that default to None in the OpenAI SDK models. The hasattr
guard is insufficient.

Fix

Add is not None checks alongside hasattr:

# WebSearchTool
if hasattr(tool, "user_location") and tool.user_location is not None:
    parameters["user_location"] = tool.user_location.__dict__

# FileSearchTool
if hasattr(tool, "filters") and tool.filters is not None:
    parameters["filters"] = tool.filters.__dict__

if hasattr(tool, "ranking_options") and tool.ranking_options is not None:
    parameters["ranking_options"] = tool.ranking_options.__dict__
