Code Execute — Input & Output

Output Ports

Port	Condition	Description
success	Script completed within timeout without throwing	`output.NodeName.result` contains whatever value was assigned to the `result` variable in the script.
error	Script threw a JavaScript exception, timed out, or triggered a sandbox violation	Error details in `output.NodeName.error`. The error includes the script error message and, where possible, the line number.

Output Data

Field	Type	Description
`result`	any	The value of the `result` variable at the end of script execution. Can be a string, number, boolean, object, or array. If the script completes without setting `result`, this field is `undefined` (not an error).

Always Set result

If your script does not assign a value to result, the success port still fires but output.NodeName.result will be undefined. Downstream nodes that attempt to use this value may behave unexpectedly. Always ensure every code path assigns result before the script ends.

Example Script Output

// Script: result = { tier: "gold", discountPct: 10 };
// Node output:
{
  "result": {
    "tier": "gold",
    "discountPct": 10
  }
}

// Downstream access:
// {@ output.CalculateTier.result.tier }        → "gold"
// {@ output.CalculateTier.result.discountPct } → 10

Error Output Schema

{
  "error": {
    "code": "SCRIPT_EXECUTION_ERROR",
    "message": "ReferenceError: 'undeclaredVar' is not defined (line 3)",
    "node": "CalculateCustomerTier",
    "scriptLine": 3,
    "timestamp": "2026-05-23T10:34:12Z"
  }
}

// Timeout error:
{
  "error": {
    "code": "SCRIPT_TIMEOUT",
    "message": "Script exceeded maximum execution time of 5000ms",
    "node": "MyCodeNode",

  }
}

Downstream Access Patterns

Expression	Returns
`{@ output.MyScript.result }`	The entire result value (object, array, or scalar)
`{@ output.MyScript.result.tier }`	A property of the result object
`{@ output.MyScript.result[0] }`	First element if result is an array
