To debug a flow, open it in Flow Builder and click the Debug button in the toolbar. This launches the debug mode where you can simulate running the flow with test data. You can enter sample values for input variables and see how the flow processes each element step by step.
The debug panel displays valuable information including the path the flow takes through decision elements, the values of variables at each stage, and any fault messages that occur. This visibility helps administrators pinpoint exactly where issues arise within complex flows.
Key debugging features include:
1. **Run Latest Version vs Previous Versions**: You can choose to debug either the latest saved version or an activated version, helping compare behavior between iterations.
2. **Rollback Mode**: Debug sessions can be configured to roll back database changes, preventing test data from affecting your org during troubleshooting.
3. **Debug Details Panel**: Shows element-by-element execution, including which resources were created, updated, or deleted, along with specific field values.
4. **Fault Paths**: When errors occur, the debug log reveals the fault message, helping you understand DML errors, null pointer exceptions, or limit violations.
Best practices for debugging include using descriptive API names for elements, adding fault connectors to handle errors gracefully, and testing with various data scenarios to ensure robust flow behavior.
Administrators should also leverage Debug Logs from Setup for scheduled flows or flows triggered by other users. These logs provide detailed execution information that complements Flow Builders native debugging tools.
Mastering flow debugging ensures your automations run reliably and helps reduce time spent troubleshooting production issues.
Debugging Flows: A Comprehensive Guide for Salesforce Administrators
Why Debugging Flows is Important
Debugging flows is a critical skill for Salesforce Administrators because flows can become complex and may not always behave as expected. When a flow fails or produces incorrect results, you need to identify the root cause quickly to maintain business operations. Effective debugging saves time, reduces user frustration, and ensures your automated processes run smoothly. On the Salesforce Administrator exam, understanding debugging techniques demonstrates your ability to troubleshoot real-world automation challenges.
What is Flow Debugging?
Flow debugging is the process of identifying, analyzing, and resolving errors or unexpected behavior in Salesforce Flows. Salesforce provides built-in debugging tools that allow administrators to:
• Run flows in debug mode to observe execution step by step • View variable values at each stage of the flow • Identify which elements succeed or fail • Understand the path the flow takes through decision elements • Review fault paths and error messages
How Flow Debugging Works
Using the Debug Feature in Flow Builder:
1. Open Flow Builder - Navigate to Setup → Flows and open the flow you want to debug
2. Click the Debug Button - Located in the button bar at the top of Flow Builder
3. Set Input Variables - If your flow requires input variables (like a Record ID for record-triggered flows), enter test values
4. Choose Debug Options: • Run the latest version - Tests the current saved version • Show details of what's executed - Displays variable values and element results • Roll back all changes - Prevents test data from being saved (useful for testing)
5. Review the Debug Log - After execution, examine each element's results, including: • Input and output values • Which path was taken at decision elements • Any fault messages that occurred
Common Debugging Scenarios:
• Null Pointer Errors - Occur when trying to access a field on a null record • SOQL Query Issues - Get Records elements returning no results or too many results • Loop Problems - Infinite loops or incorrect iteration logic • Formula Errors - Incorrect syntax or data type mismatches • Decision Logic Errors - Conditions evaluating unexpectedly
Key Debugging Tools and Features
• Flow Debug Log - Shows step-by-step execution details • Debug Email for Failed Flows - Sends email notifications when flows fail in production • Fault Connector - Allows you to handle errors gracefully and capture error messages • Setup Audit Trail - Tracks changes made to flows • Flow Error Emails - Configured in Process Automation Settings to notify admins of failures
Best Practices for Debugging Flows
1. Always use the Roll back mode when testing with production data 2. Add fault paths to elements that interact with data 3. Use meaningful variable names to make debugging easier 4. Test with various input scenarios including edge cases 5. Check Governor Limits when dealing with large data volumes 6. Review the $Flow.FaultMessage and $Flow.InterviewGuid system variables for error details
Exam Tips: Answering Questions on Debugging Flows
Key Concepts to Remember:
• The Debug button in Flow Builder is the primary tool for testing flows • Fault connectors allow you to create error handling paths • The "Roll back" option prevents test data from persisting in the database • Flow error emails can be enabled in Process Automation Settings • Debug mode shows variable values and execution paths
Common Exam Question Types:
1. Scenario-based questions - You may be given a flow that isn't working and asked to identify the debugging approach 2. Feature identification - Questions about which tool to use for specific debugging needs 3. Error handling - Questions about fault connectors and error email configurations
Exam Strategies:
• When a question mentions a flow producing unexpected results, think about the debug feature first • If asked about production error monitoring, remember flow error email notifications • For questions about preventing test data from being saved, the answer involves the rollback option • Pay attention to whether the question asks about testing in Flow Builder versus monitoring production flows • Remember that fault paths are essential for graceful error handling
Watch Out For:
• Distinguish between debugging during development (Flow Builder debug) and monitoring production issues (error emails, fault paths) • Questions may test whether you understand that inactive flows cannot be debugged in the same way as active ones • Know that Record-Triggered Flows require a valid Record ID to debug properly
