I can see that you're using the MQTT Sparkplug out node. What is the destination you want to send the data to? If you are publishing data for the MQTT Engine Module in Ignition, then you should use the MQTT Sparkplug Device node.
My second question is; what is the reason why you want to send is_historical data in the first place? is it because you don't have access to realtime data from Node-Red and are pulling historical data at a fixed interval? or is it because you have created you own store-forward buffer system? or something else?
