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

1. Open the failed execution and compare the iteration summary with the step output.
2. Check whether the failing iteration maps to a specific DPL row or input value.
3. 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.
