Troubleshoot Iteration Summary Error Messages
Last reviewed: September 28, 2026
Use this article when an AIQ execution shows an iteration-summary error and the team needs to identify whether it came from data, playback, or reporting.
What changed in this article
- Changed the article from a vague error-message title into a troubleshooting workflow.
- Added checks for DPL row availability, failed assertions, step-level output, report generation timing, and execution logs.
- Clarified that the iteration summary is an investigation entry point, not the only source of failure evidence.
Validation workflow
- Open the failed execution and compare the iteration summary with the step output.
- Check whether the failing iteration maps to a specific DPL row or input value.
- Review report/output logs before changing the scenario logic.
Review note: This now helps triage data-driven iteration failures instead of just naming the error.
