Invalid or Unsupported Model: The agent failed because the configured model name is invalid, unknown, or unavailable for this engine/account.
This is a configuration issue, not a transient error — retrying will not help.
How to fix this
Specify a valid model for the selected engine in the workflow frontmatter:
---
engine: copilotmodel: gpt-5-mini
---
To find valid models, check your engine/provider documentation (for Copilot see supported models).
If the error text is No model available. Check policy enablement under GitHub Settings > Copilot, the model is not disabled in the workflow but by Copilot policy. Enable the model under GitHub Settings > Copilot > Policies for the org/repo, or pick a model that is already enabled. This can also be triggered by a subagent (task tool) dispatch requesting a model that the policy does not allow, even when the main agent's model is enabled.
Warning
Engine Failure: The copilot engine terminated unexpectedly.
