@Chidi_251 Please, how did you delete the database?

@makama-md go to your project folder and you will see events and rasa .db file delete it and again run the rasa x.

I had the same problem today after I reinstalled rasa x, which was previously running without any problem. I believe the problem is not caused by installation(since there is no error during the installation process). It is caused by the old database file from your previous rasa x.

Therefore, the solution is to create a new rasa project with “rasa init” or simply delete residual database files.
