AWS quick documentation change

Service: quick · 2026-04-22 · Documentation low

File: quick/latest/userguide/troubleshooting-knowledge-bases.md

Summary

Added new troubleshooting section for 'ACL validation errors' and updated file format/size references to point to a centralized limits page.

Security assessment

The change adds documentation about ACL (Access Control List) validation errors, which are related to authorization and permissions. This helps users troubleshoot security configuration issues with knowledge base connectors, specifically when ACL permissions are missing. However, there is no evidence this addresses a specific security vulnerability or incident; it's general troubleshooting guidance.

+## ACL validation errors
+
+If your sync report shows items with status **SKIPPED** and error type **VALIDATION_ERROR** with the message "File has no ACL while crawlACL is true, skipping ingestion," the app registration used by your knowledge base connector is missing the required ACL permissions.
+
+**To resolve:**
+
+  1. Verify the app registration has the correct API permissions for ACL crawling. The required permissions vary by connector. See the permissions section in your connector's setup documentation.
+
+  2. Confirm that admin consent has been granted for all required permissions.
+
+  3. Re-run a full sync after fixing permissions.
