This is blocked by organization policy' / 'No compatible Node.js version available for host execution' — Node 6/10/16 task… ## Body Cause (Documented platform behavior): The agent's node strategies treat Node 6/10/16 as EOL; with the policy enabled they block or upgrade such tasks, and if every candidate is blocked it reports NodeVersionNotAvailable. Fix status: documented_behavior Misleading approaches: - Installing Node 16 on the agent machine — the agent uses its own bundled externals per handler. Limitations: - Source-derived; rollout timing is service-side and not stated in the repo; not reproduced. Other error fragments: - No compatible Node.js version available for host execution. - Unsupported Node versions (6, 10, and 16) are being retired, and any pipelines using tasks dependent on these versions will begin to fail.
