Troubleshooting Common Post-Deployment Issues in AEM
Introduction
Deploying code to Adobe Experience Manager (AEM) can sometimes lead to unexpected issues. This article outlines common problems encountered after deployment and their solutions.
Common Issues and Solutions
- Blank Page Issues
- Problem: After deployment, AEM pages load as blank.
- Root Cause: This can be due to missing or incorrect client libraries, component errors, or backend issues.
- Solution: Check the error.log file for specific errors. Ensure that all client libraries are included and compile correctly. Verify that components are correctly deployed and there are no backend exceptions.
- Component Not Rendering
- Problem: Newly deployed components not appearing on pages.
- Root Cause: Often due to issues in component code or dialog definitions.
- Solution: Validate the component’s HTL/Sightly code and dialog definitions. Check for any errors in the browser console and AEM error logs.
- Service Pack Installation
- Problem: Issues persisting even after code fixes.
- Root Cause: Compatibility or known bugs that are fixed in newer service packs.
- Solution: Identify the appropriate service pack for your AEM version. Service packs can be found on the Adobe Experience Manager Releases page. Follow Adobe’s guidelines for installing service packs.
- Performance Issues
- Problem: Slow page loading or performance degradation.
- Root Cause: Inefficient code, large page sizes, or server configuration issues.
- Solution: Optimize code, compress and optimize images, and review server configurations. Consider using dispatcher caching for better performance.
Conclusion
Effective troubleshooting in AEM requires a systematic approach to identify and address issues. Regularly updating to the latest service packs and maintaining clean, efficient code are key practices for a smooth AEM experience.
