[BUG] RuntimeError: dictionary changed size during iteration when running Strix in TUI mode

[reza-seidgar]

Hi,
While running a penetration test with Strix in TUI mode, the program crashes during the Dynamic Test phase with the following error:
RuntimeError: dictionary changed size during iteration

After this error, the TUI session closes automatically and the test is marked as interrupted. The session folder is created under ~/strix/agent_runs/, but it remains empty and no report file is generated.

How to reproduce:
Run a normal Strix test in TUI mode using any valid target.
Static Analysis completes successfully.
During the Dynamic phase, TUI crashes with the error above.

Expected behavior:
TUI should remain stable
The Dynamic Test should complete
Report files should be generated

Actual behavior:
TUI crashes
Session ends prematurely
No report file is produced

Environment:
Ubuntu 22.04
Python 3.12
Strix installed via pipx

Thanks!

Hi @reza-seidgar
Thanks for reporting the issue!

Which version of Strix do you have installed?

I'm having exactly the same issue, running:
Strix 0.4 installed via pipx
on Ubuntu 24.04
with Python 3.12.3.

The error appears to occur here
/pipx/venvs/strix-agent/lib/python3.12/site-packages/strix/interface/tui.py:485 in _update_ui_from_tracer
/pipx/venvs/strix-agent/lib/python3.12/site-packages/strix/interface/tui.py:556 in _update_chat_view
/pipx/venvs/strix-agent/lib/python3.12/site-packages/strix/interface/tui.py:788 in _gather_agent_events
