Python: [Bug]: devui

[NicoVermeir]

Description

DevUI is throwing an error in a workflow:

2026-02-16 15:36:45 [ERROR] agent_framework_devui._executor: Error in workflow execution: Sorry, something went wrong.
2026-02-16 15:36:45 [ERROR] agent_framework_devui._tracing: Error setting up trace capture: 'dict' object has no attribute 'type'
2026-02-16 15:36:45 [ERROR] agent_framework_devui._executor: Error executing entity workflow_basic: generator didn't stop after throw()
Traceback (most recent call last):
  File "d:\Demos\PythonAgents\.venv\Lib\site-packages\agent_framework_devui\_tracing.py", line 152, in capture_traces
    yield collector
  File "d:\Demos\PythonAgents\.venv\Lib\site-packages\agent_framework_devui\_executor.py", line 267, in execute_entity
    if event.type == "request_info":
       ^^^^^^^^^^
AttributeError: 'dict' object has no attribute 'type'

The error comes from the devUI code itself. I think it might be due to version mismatch between agent-framework and agent-framework.devui but that can't be resolved due to conflicts.

To reproduce:

• Create a new venv
• pip install agent-framework
• pip list

Package                                  Version
---------------------------------------- ------------
agent-framework                          1.0.0b251120
agent-framework-core                     1.0.0b251001

• pip install agent-framework.devui
• pip list

Package                                  Version

agent-framework-core                     1.0.0b260212

core package has been upgraded

• pip install -U agent-framework==1.0.0b260212

ERROR: Cannot install agent-framework-core[all]==1.0.0b260212 and agent-framework==1.0.0b260212 because these package versions have conflicting dependencies.

The conflict is caused by:

Just in general, without looking at the issue, agent-framework is just a meta package that install agent-framework-core[all] in this case the relevant thing we need to debug is the versions of core and devui packages. Can you share those?
