member graph run failed: {e}

Error message

member graph run failed: {e}

What it means

The tinyagents graph engine returned an error while driving an agent-team member's execution graph (built by build_member_graph with execute/complete/fail/done nodes and a GraphTracingSink). This wraps the engine-level failure of the whole member run — node panic, engine limit, or an error propagated through graph_err from the on_complete/on_failed callbacks — as it propagates out of the team-member execution driver.

Solutions

1. Inspect the GraphTracingSink trace events for the member label to find which node failed
2. Handle the member as failed via the graph's fail path (on_failed) so the team records the failure instead of hanging
3. Fix the underlying worker/callback error identified in the trace and re-drive the member
