Hi everyone I've noticed none of the NLU utterances are working while testing the bot, and the topic only "runs" when I selected the topic from the "show me everything" button. I'm starting to believe the NLU model isn't working as it's not picking up any phrases.
So when attempting to train the ITSM NLU model I get a generic error (training failed). When I attempt to try the model with utterances I get the following error code - 

Exception caught in the predict call - reason: {"status":"failure","exception":"sn_ml.MLServiceUtil.predict(): java.lang.Exception: ModelInfo artifact not present for key : 5afcd79c47b431149efe7488436d437f_.modelInfo_9"}

I've tried searching around but can't get my head wrapped around this. Anyone got any pointers?

Hello Christopher13.  The error "ModelInfo artifact not present for key" may occur when an instance is cloned but the artifacts do not get transferred.  Did you clone before this happened?
- Try disabling "Exclude large attachment data".
- Additionally, make sure to set glide.platform_ml.clone_artifacts to true.
