Error Handling

When building workflows in Agentic Workflow Studio, you may encounter situations where a step fails — for example, a web request might time out, a page element might not load, or an API might reject a request.
Error handling lets your workflows recover gracefully instead of stopping completely.

Common Workflow Errors

Here are some common error types you may encounter in browser automation or API workflows:

• Content Security Policy (CSP) violations: Some websites block actions from browser extensions.
• DOM element not found: When a webpage layout changes and selectors no longer match.
• Cross-origin restrictions: Accessing data from other domains may fail.
• Page loading or timeout errors: Slow network conditions or missing elements cause timeouts.
• Permission errors: Browser or API credentials may lack the necessary access rights.

Create an Error Path

Each node can have an error path — a dedicated branch that runs when that node fails.
This allows your workflow to handle issues intelligently, such as retrying, sending a notification, or logging the error.

For example:

flowchart LR
    A["Fetch Data"] L_A_B_0@-- Success --> B["Process Data"]
    A L_A_C_0@-- Error --> C["Send Alert Email"]
    n1[" "] L_n1_A_0@--> A
    n1@{ icon: "fa:circle-play", pos: "b"}
    L_A_B_0@{ animation: slow } 
    L_A_C_0@{ animation: slow } 
    L_n1_A_0@{ animation: slow }

In this example, if “Fetch Data” fails, the workflow continues through the error path to “Send Alert Email”.

Best Practices for Error Handling

• Use retries wisely: Add delay or exponential backoff when retrying failed requests.
• Log and monitor errors: Capture context about failures for debugging.
• Handle expected errors: For example, use conditional nodes to catch known API failure responses.
• Use the Error Trigger node: To start workflows when any other workflow fails.

Debugging Browser Workflows

If your browser-based workflow fails:

1. Open your Execution History in Agentic Workflow Studio.
2. Check the Browser Console Logs for JavaScript or network errors.
3. Verify that the target page still contains the same elements or structure.
4. Confirm that your extension permissions are correctly configured.

These steps can help identify whether the issue is with your workflow logic or external factors.
