Describe the bug
I am successfully able to call agents as tools and ultimately call an agent that uses the WebSearch tool just fine. However the minute I change that agent to be a handoff. I see a strange error
Error code: 400 -
{'error': {'message': "Invalid 'input[1].id': '__fake_id__'. Expected an ID that begins with 'msg'.", 'type': 'invalid_request_error', 'param': 'input[1].id', 'code': 'invalid_value'}}
I included a picture of the logfire traces to show how in the first scenario with an error it is using a handoff. In the second it is using an agent as a tool
I also included how the websearch tool is definitely working and you can see it being called internally in the second picture. So i am left unsure why it would work fine in an agent as tool call but not in a handoff
Debug information
- Agents SDK version: 0.0.19
- Python version: 3.11.5
Repro steps
Hard for me to give you a python script for this. But the example was the following
Create a parent orchestrator
Create a child orchestrator with a function call to WebSearch
Parent Orchestrator uses claude
Child Orchestrator uses gpt4.1
First try assigning child orchestrator as a tool
Then try assigning it as a handoff in the parent
You ca n see
