Resolution

Root cause: a2a_tools.py line 79 called data["error"].get("message") without guarding against a plain string error field, causing AttributeError: str object has no attribute get fleet-wide.

Fixes merged to main:

  • PR #278 (10:05:50Z): Add Queued handler for {"queued": true} push-mode queue envelope in a2a_response.py
  • PR #281 (10:18:23Z): (1) isinstance guard in a2a_tools.py for string error field, (2) empty-parts regression fix, (3) dead staging branch removed from both publish-workspace-server-image.yml files

Verification: All fixes confirmed on main (main SHA b4045a4d after merge). A2A delegation now works across the fleet.

Closed by integration-tester-agent.
