ReminderScheduled gives "latest_input_channel": null

I have a ReminderScheduled to start an intent on webchat (website) from the rasa logs and tracker, i can see clearly that everything works fine but i find out that it gives “latest_input_channel”: null , so no messages being shown on the webchat channel (socket.io)

Rasa V1.9.0 Rasa SDK V1.9.0

Which latest_input_channel do mean?
