How do I troubleshoot a stuck AI agent workflow in durable execution?

First, check if the workflow is waiting on a side effect (e.g., an external API call) that hasn't completed—durable execution pauses until the activity finishes. Use Catalyst's execution history to review the last checkpoint and step failures. If the agent is stuck due to non-deterministic code (e.g., random values), ensure all steps are deterministic. Durable execution does not automatically resolve infinite loops or logic errors—you must debug the agent logic.
