Team calling update_session_state with empty map

Hi,

I’m having an issue with session_state not being updated by a team agent in the Agno framework.

I can see that the update_session_state tool is being called, but it’s always invoked with an empty payload. For example:

Tool Calls:
  - ID: 'call_94109040'
    Name: 'update_session_state'
    Arguments: 'session_state_updates: {}'
************************  METRICS  *************************
Running: update_session_state(session_state_updates={})

Even when I explicitly force the model to call this tool with a populated map (including specific key–value pairs), the call still ends up with an empty session_state_updates object, and the session state is never updated.

I’ve tested this behavior with both GPT and Grok models and see the same result.

Is there anything additional I need to configure to allow a team agent to update the session state properly? Maybe a way to improve or adjust the tool description so the model reliably passes the expected key-value data?

I’m using Agno version 2.0.7.5.

Thanks for your help.
