@dpavanreddy are you using docker or just running on local machine?

@dpavanreddy If you are using local machine delete .db files of events and rasa from project folder.

OR

if you are using docker same delete files and then build the image.

I hope you got my points? If you have any issue do let me know. Good Luck!

its productions we are using rds postgresql instance, by deleting whole data will be lost. And “if you are using docker same delete files and then build the image” is it like fresh install?(already tried not working)
