Summary

Executes a supplied JavaScript function in the browser page routed by the selected remote port, and returns the function’s result when a response is received.

Inputs

• Topic (required) — MQTT topic used to publish the request to the client.
• QoS — MQTT delivery level; defaults to 1 (at least once).
• Include Input Items — When enabled, attaches selected fields from incoming workflow items as payload.inputItems.
• Include Input Fields — Comma-separated field paths to include from incoming items, including nested paths and array indexes; shown when Include Input Items is enabled.
• Wait For Response — When enabled, waits for the MQTT response before continuing; defaults to false.
• Response Timeout (sec) — Maximum response wait time in seconds when waiting is enabled; defaults to 60.
• Delay Next Step (ms) — Delay before continuing after the response, or after publishing when not waiting; defaults to a random 200–1000 ms expression.
• Remote Port (required) — CDP port used to route the JavaScript action to the intended browser session. Commonly connected from the node that opened the profile; 127001 denotes a local session.
• Script (required) — JavaScript function written as an arrow function and executed in the page context, such as () => document.title. Its returned value becomes the action result.
• Arg (JSON) — Optional JSON value passed as the script function’s argument; can be an object, array, or incoming item data.

Output shape

A workflow item containing the JavaScript action result when a response is received.

The action is sent over MQTT. The operation defaults to not waiting for a response; enable Wait For Response to receive the result before continuing. When not waiting, the node proceeds after publishing and the configured delay.
