The error is most likely raised by incompatible Rasa Open Source version within Rasa X. user_featuraization is a new event type introduced in rasa open source 2.2.1. Rasa X may have a lower version of Rasa Open Source and hence it cannot read the new event type. Could you try poetry update?

Aside from the user_featurization issue, I am having a similar problem and wrote about it in this thread here: "There was an error loading messages and polling has been stopped."

My Rasa version is 2.4.0 and Rasa-X is 0.38.1 which are compatible.

@RGK do you have other instances where the conversations are not affected and the since parameter is set to a number other than 0?
