Common Issues in Blue Prism
Blue Prism-related problems often arise due to incorrect application model configurations, environment settings, credential vault misconfigurations, or inefficiencies in bot design. Identifying and resolving these challenges improves automation stability and efficiency.
Common Symptoms
- Bots fail to execute or complete tasks.
- Errors when interacting with external applications.
- Issues with retrieving or storing credentials.
- Process execution is slow or inefficient.
- Database and session logs indicate performance bottlenecks.
Root Causes and Architectural Implications
1. Bot Execution Failures
Incorrect process logic, missing dependencies, or session configuration errors can cause bot failures.
# Check session logs for errors SELECT * FROM BPASessionLog WHERE Status = 'Failed';
2. External Application Connectivity Issues
Misconfigured application models, UI changes in target applications, or incorrect region settings can break bot interactions.
# Refresh application model in Object Studio Application Modeller > Reload Application
3. Credential Management and Security Failures
Issues retrieving credentials from the Blue Prism Credential Manager or incorrect access permissions can cause authentication failures.
# Verify credential settings System Manager > Security > Credentials
4. Performance Bottlenecks
Inefficient bot design, excessive database queries, or long execution loops can slow down processes.
# Optimize process execution Remove unnecessary wait stages and optimize loops
5. Object and Process Configuration Errors
Improper object linking, incorrect input/output parameters, or missing decision stages can lead to unexpected process failures.
# Validate object references Studio > Process Validation
Step-by-Step Troubleshooting Guide
Step 1: Debug Bot Execution Failures
Check process flow for missing actions, validate session logs, and ensure all required dependencies are loaded.
# Restart a failed session UPDATE BPASession SET Status = 'Restart' WHERE Status = 'Failed';
Step 2: Fix Application Connectivity Issues
Ensure application models are updated, adjust UI element recognition, and verify that target applications are accessible.
# Test application connectivity Use Application Modeller to refresh element identifiers
Step 3: Resolve Credential Management Problems
Verify that credentials are stored correctly, check access permissions, and reconfigure credential retrieval settings.
# Reset credential permissions Security > Credentials > Edit Permissions
Step 4: Optimize Process Performance
Reduce wait stages, minimize unnecessary loops, and implement efficient decision logic.
# Analyze process execution time View Execution Logs in Control Room
Step 5: Validate Object and Process Configurations
Ensure correct input/output parameters, validate business rules, and check for missing process links.
# Run process validation Studio > Process Validation Report
Conclusion
Optimizing Blue Prism automation requires addressing bot execution failures, ensuring proper connectivity, managing security credentials efficiently, optimizing performance, and validating process configurations. By following these best practices, businesses can maintain reliable and scalable RPA workflows.
FAQs
