Describe the bug
We are testing out Letta Groups in a sandbox environment and are consistently running into backend errors when sending messages to groups. This happens with multiple group types (Supervisor, RoundRobin, and Dynamic).

Please describe your setup
Environment
Client: letta-client 0.1.324 (from PyPI)
Server: Letta Cloud (v0.11.7)
Python: 3.13
OS: macOS

Steps to Reproduce
# Example: create a RoundRobin group and send a message

response = client.groups.messages.create( group_id=group.id, messages=[{"role": "user", "content": "Hello group, please each give me an update on your user."}] )

Errors Observed
Supervisor group: Can't instantiate abstract class SupervisorMultiAgent without an implementation for abstract methods 'step', 'step_stream'

RoundRobin and Dynamic groups: 'name 'Agent' is not defined'
