What is the difference between Run and Debug modes in Flow Builder?

In Flow Builder, Run and Debug modes have distinct functionalities:

Run Mode:

Executes the flow as it is, allowing you to see the end-to-end execution based on the latest saved version.

Typically used to verify that the flow works as expected under normal conditions.

Debug Mode:

Provides detailed information for each step of the flow, including input and output data, and any errors encountered.

Useful for troubleshooting and identifying issues within the flow, allowing developers to understand how the flow executes and where problems may arise.

Debug mode is specifically designed to aid in diagnosing and fixing issues by providing a granular view of the flow's execution.
