To debug a flow instance, use the replay controls to navigate across flow execution items (actions, tasks, or menus) in the replay timeline at the bottom of the page. The controls allow you to move back and forth to any point in the flow execution history. Replay actions are available from the toolbar and via customizable keyboard shortcuts. To change the default keyboard shortcuts, click  Preferences.

Replay command	Description	Keyboard shortcut
Play or pause	Replay the flow instance from start to end, or to pause the replay. To select the playback speed, click and select the appropriate speed. You can choose between Fast, Default, and Slow. Note: If you already stepped through several items, the play command plays forward from the flow execution item you are currently on until the end or the next breakpoint if a breakpoint exists.	Control + F7
Step In	Step forward to the next flow execution item and enter into it to follow its execution step by step.	F11
Step Over	Step forward to the next flow execution item and follow its execution without showing any component steps.	F10
Step Out	When inside a flow execution item, complete any remaining component steps as a single step to step forward to the next flow execution item.	F9
Step Back In	Step backward to the previous flow execution item and enter into it to follow its execution step by step.	Control + F11
Step Back Over	Step backward to the previous flow execution item and follow its execution without showing any component steps. Execution replay stops when it encounters a breakpoint.	Control + F10
Step Back Out	Step backward to the previous flow execution item from inside a flow execution item.	Control + F9
Play to End	Resume flow execution replay up to the next breakpoint or until the end.	Control + F6
Play backwards to Start	Play backwards to the start of the flow or a previous breakpoint if a breakpoint exists.	Control + F4
Set or clear a breakpoint	Insert a breakpoint where you want the flow execution replay to stop. Remove a breakpoint you previously set.
	Use the up and down arrows to navigate between execution items.

In the replay mode’s timeline tab at the bottom of the page, you can inspect and debug all flow execution items, and navigate across them. The following replay actions are available:

• Click the flow execution item (flow start, action, task, menu, or flow end) that you want to inspect. Architect displays the flow execution item in replay mode and highlights it in purple in the editor or design area. You can also use the replay controls to navigate between the items. For more information, see Use the replay controls.

• Hover over the flow execution item that you want to inspect. Architect displays various information depending on the execution item that you want to inspect:
  
  • Flow Started: Architect displays the flow execution ID, the flow’s starting language, and the flow’s start time. Flow Execution ID is the unique identifier that Architect uses to identify an instance of a flow that ran. Architect also displays whether the flow ran in a secure session or whether the flow was truncated because it contained more than 4,500 actions. Additionally, the Flow Started event displays the following memory usage values in email, messaging, and workflows flow types:
    • Current User-Variables Size: Memory currently used by the user-defined variables in the flow at this point. This value appears on other events and the Flow Ended event in the replay timeline. 
    • Max User-Variable Size: The peak size those variables reached so far during the execution. Flows have limits on variable memory, so this helps you spot variables growing too large. The maximum limit is 48,000 bytes. Click its name to view the timeline frame where the maximum was reached.
    
  • Flow Ended: Architect displays the flow’s end time and the exit reason. It also shows the user variables size at the flow’s end time in supported flow types.
  • For any other execution item, Architect displays the name and type of the action that the flow ran, the time of execution and the execution ID, the stack execution ID, the output path the flow followed, the action ID, and runtime details such as the current user variables size (in supported flow types). The stack execution ID is a unique identifier for where the execution item is in the flow’s execution stack. You can copy most of this information to the clipboard. Click to copy.

• To open the Flow Execution History dialog box, click Execution History. The dialog box gives you access to the Query Builder and, by default, to the list of flow instances whose Flow Id matches the Flow Id of the flow instance you are currently viewing. You can run a query based on other flow criteria such as Flow Error Code, Flow Warning Code, Invoking Flow Object Execution Id, or Flow Invoked Error. You can also query the historical data by Conversation Id, which is useful when there are many instances of the same conversation-based flow. For more information about building a flow execution query, see Build a flow execution history query. 
• To open the flow that invoked the flow you are viewing in replay mode, click Open Invoking Flow. This option is only available if historical execution data is available for the invoking flow. The amount of data that Architect displays for the invoking flow depends on the level of execution data at which Genesys Cloud recorded the invoking flow. Supported data types vary according to flow type. For example, you cannot see any communications data when you replay an inbound message flow, regardless of whether the execution data level at which Genesys Cloud recorded the flow would generally include such data. 
• To open the workitem that invoked the workitem flow you are viewing in replay mode, click Open Invoking Workitem. A workitem can launch a workitem flow at the creation time, on workitem status change, or when a date-based event occurs for the workitem. This option allows you to navigate to the workitem that triggered the flow instance.
• To show or hide the Stack Graph, click .
• To adjust the timeline’s zoom level from no zoom to small, medium, and full zoom, click the Zoom drop-down.
• To change keyboard shortcuts or customize the replay mode view, click Preferences.

• Architect GUIDs
• Specific actions, menus, states, or tasks
• Variables

You can use various operators to narrow down your search. To select a search operator, click and select one of the following operators:

• Contains = Architect returns all search results that contain all the characters that you specify.
• Exact = Architect returns all search results that match the characters that you specify exactly.
• Starts with = Architect returns all search results that start with the characters that you specify.

The Communications panel provides an easy way to see the entire communication thread that occurred when the flow ran. You can configure the panel to show either all communications or only communication that relates to the currently selected flow execution item.

The Communications panel is where you can see interactions between a flow and external participants. For example, message exchanges between a customer and a chat bot.

To switch between the flow’s default language and supported languages, click the down arrow next to the language filter and select the preferred language to view.

To work with element IDs, follow one of these steps:

• To show or hide element identification numbers, clickShow or hide action, menu, task, and state IDs.
• To go to a specific element, click the down menu, select Go To, and select the appropriate ID.

To find flows that reference and use the current flow, click Find consuming flows.

When the flow instance you are replaying contains secure data, Architect displays the icon. To search for execution items that reference secure data, click the icon.

Architect displays the execution data level that Genesys Cloud used to store historical data for the flow instance.

In the following example, you can see that Genesys Cloud captured execution data at flow runtime at the Base level. Therefore, the user cannot access variable value data or communications data:

For more information about historical execution data and data settings, see Historical execution data overview, Manage execution data at the flow level, and Manage historical execution data.

To export flow execution or configuration data, click Export and click one of these options:

• Export execution data
• Export as .i3xxx
• Export as .yaml

For more information on how to access replay mode for a specific flow through the Operational Console when an event is generated, see Troubleshoot using the Genesys Cloud Operational Console.
