Handoffs with gpt-5* model + store=False fails due to 404 error response #1668
Description
Describe the bug
Reasoning model like gpt-5 or gpt-5-nano cannot use the handoff feature when the store option set to False.
At the handoff-ed agent I got the following error:
"Items are not persisted when
storeis set to false. Try again withstoreset to true, or remove this item from your input."
Agent definition:
triage_agent = Agent[RunContext](
name="triage_agent",
instructions=instructions,
model="gpt-5",
model_settings=ModelSettings(
tool_choice="auto",
parallel_tool_calls=False,
store=False,
),
handoffs=[
handoff(image_agent, input_filter=handoff_filters.remove_all_tools),
],
tools=[
WebSearchTool(**web_search_tool_kwargs),

Repro steps
- Set store=False for both triage_agent and second_agent
Expected behavior
No error at the second agent.
