Summary

Publishes an MQTT request to clean temporary images downloaded or cropped by image actions on the client machine. Use it at the end of a workflow to remove those files and limit disk usage.

Inputs

• Topic (required) — MQTT topic used to route the request, such as a client-specific topic.
• Remote Port (required) — Client CDP session port used to route the request to the intended session; the UI defaults to the incoming remote_debugging_port value.
• QoS — MQTT delivery quality level: 0, 1, or 2; defaults to 1.
• Include Input Items — When enabled, adds selected fields from incoming items to payload.inputItems. Defaults to false.
• Input fields — Comma-separated field paths to include when Include Input Items is enabled; supports nested paths and array indexes.
• Wait For Response — When enabled, waits for an MQTT response before returning output; defaults to false.
• Response Timeout (sec) — Maximum wait for a response when waiting is enabled; defaults to 60 seconds.
• Delay Next Step (ms) — Delay before continuing after publish, or after the response if waiting is enabled; defaults to a random 200–1000 ms delay.

Output shape

A list of items representing the MQTT response when waiting is enabled; otherwise the operation publishes the request and continues without waiting for a response.

The request is sent to the configured topic and session port. Selected incoming fields may be attached as payload.inputItems. The exact response item shape is not specified by the supplied source view.
