Rasa X bot not responding

Hi all,

I installed Rasa X in Kubernetes via helm chart and it is running fine. However, when I upload and activate a pretrained rasa model then talk to the bot, the bot wouldn’t respond at all. I can only see 3 dots keep loading. I looked at the logs of the rasa-production pod and below is the output of the logs. It appears that it is not able to find the spacy model en_core_web_lg.

Any pointers?
