Try & Runs

Test functions with sample data, inspect variables, and review execution history.

Try & Runs

Use Try to test a function with sample data, inspect variables, and review each execution. This helps you catch missing inputs, broken conditions, and unexpected API responses before publishing.

Try a function

Open the function

Go to Functions and open the function you want to test.

Click Try

Click the Try button in the toolbar.

Set test inputs

Fill in sample data for the request body, path parameters, or query string - whatever your function expects.

Run and inspect

Run the function and inspect each step result. The run view shows outputs, variables, and errors.

Set breakpoints

Breakpoints pause execution at a specific step so you can inspect the variable state.

1. Hover over a step in the editor
2. Click the dot that appears on the left edge
3. A red dot confirms the breakpoint
4. Try the function - it pauses at the breakpoint

When paused, you can:

| Control        | What it does                                     |
|---------------|--------------------------------------------------|
| Continue  | Run until the next breakpoint or the end         |
| Step Over | Execute just this step, then pause again          |
| Stop      | Cancel the function run                           |

Inspect variables

The variable inspector shows every variable and its current value after each step. You can see:

- vars — Variables you set during the function run
- input — The request body
- params — Path parameters
- query — Query string values

Objects and arrays can be expanded to drill into their contents.

Pro tip

Use step-by-step execution (click Step Over repeatedly) to walk through a function without setting breakpoints. The inspector updates after each step.

Troubleshooting tips

Variable is undefined?
Check that the step assigning it actually runs. It might be inside an If/Else branch that was not taken.

Database query returns empty?
Use the variable inspector to check your WHERE condition values. Then verify the data exists using the Data tab in the Database section.

API call fails?
Inspect the URL, headers, and body in the variable inspector. Check that env variables like API keys are set correctly.

Execution history

Open Runs from the resource menu to review previous executions. Endpoint, task, trigger, and function runs can include:

- Duration, status (success/error), and timestamp
- The full request and response data
- Step-by-step execution logs
- Analyze with AI — click to send an error directly to the AI Copilot for diagnosis
