Session terminates prematurely at step N-1, causing infinite retry loop at step N #23
Description
Summary
When running a multi-step plan (e.g., 10 steps), the session terminates at the end of step N-1, but the control loop still attempts to execute step N. This causes a 'NoneType' object has no attribute 'name' error, which triggers an infinite retry loop with no retry limit. I have had this error twice.
Steps to reproduce:
- Create a plan with 10 steps using
planning_and_control_context_carryover() - Execute the plan - steps 1-9 complete successfully
- At the end of step 9, observe that step 10 is marked as "completed ✅" before it runs
- Session terminates
- Step 10 still tries to execute on the terminated session
- Error occurs, retries indefinitely
The logs:
End of step 9 (chat_output_researcher_step_9.json):
{
"content": "**Step number:** 10 out of 10... **Status:** completed ✅"
},
{
"name": "terminator",
"content": null
},
{
"name": "_Group_Tool_Executor",
"content": "Session terminated."
}
Step 10 (chat_output_researcher_step_10.json):
{
"name": "control_starter",
"content": null
},
{
"name": "_Group_Tool_Executor",
"content": "Error: 'NoneType' object has no attribute 'name'"
}
// Repeats 50+ times
### Expected Behavior:
1. Session should not terminate until ALL steps have actually executed, OR
2. Control loop should not attempt to run step N after session termination, OR
3. A retry limit should prevent infinite loops on unrecoverable errors
