As mentioned here

Ui-table supports ui_control

Hi Andy, Rows is not a JavaScript object per se it is a component which can not be transferred to a JSON formatted sting. You can/should access the data by the included methods. This is why the send method fails. You can pick the relevant data by using the methods in a new object and send this back to the runtime. Here is an example for the cell component So your error is not directly related to the loopback issue - your error is caused by trying to convert a component to a json string. …

Rows is a component and can‘t be converted into a JSON string to be sent from the frontend to the backend (node-red)

You have to use the methods to pic the data items.
