    </dl>

    <h3>Details</h3>
    <p>The node can receive a JSON with the parameters described in the Inputs section and with them generate the output JSON.
        If the values are not present in the input JSON, these are read by those in the configuration. If they are not present
        in either part, an error is generated for the necessary parameters.</p>
