I run `rasa x`. Then, an error is triggered but I don’t know how to overcome it.

```
rasa.core.tracker_store - 

```

Error happened when trying to save conversation tracker to ‘InMemoryTrackerStore’. Falling back to use the ‘InMemoryTrackerStore’. Please investigate the following error: (sqlite3.OperationalError) attempt to write a readonly database

```
[SQL: INSERT INTO events (sender_id, data) VALUES (?, ?)]

ISSUE : the ‘events.db’ is set as ‘read-only’

SOLUTION : unset the ‘read-only’ attribute
