GREAT LOTUSInstall

Summary

Publishes an MQTT request to retrieve the HTML of an iframe by its index, without switching to the iframe first. Optionally waits for the response and returns it with the workflow items.

Inputs

• Topic (required) — MQTT topic used to publish the request.
• Remote Port (required) — CDP port used to route the request to the intended client session; can be mapped from an upstream node's remote debugging port.
• QoS — MQTT delivery quality level: 0, 1, or 2; defaults to 1.
• Include Input Items — When enabled, includes selected fields from incoming items in payload.inputItems.
• Input fields — Comma-separated field paths to copy into the request when Include Input Items is enabled; supports nested paths and array indices.
• Wait For Response — When enabled, waits for an MQTT response before returning; defaults to false.
• Response Timeout (sec) — Maximum response wait time in seconds; shown when waiting is enabled and defaults to 60.
• Delay Next Step (ms) — Delay before continuing after publishing, or after receiving a response if waiting is enabled; defaults to rand(200,1000).
• Index — Zero-based iframe index to retrieve; defaults to 0.

Output shape

A list of workflow items containing the MQTT response when waiting is enabled; otherwise the operation publishes the request and returns without a response body.

The source pack shows only a signature-level view of the implementation, so response parsing and exact output fields are not visible.
