SQLite objects created in a thread can only be used in that same thread with Django 2.2.2 and ipdb

I updated my Django project to version 2.2.2 and now when I call to ipdb for debugging, the server tell me that error. If I go back to Django 2.2.1, the error disappears.
System check identified no issues (0 silenced).

sqlite3.ProgrammingError: SQLite objects created in a thread can only be used in that same thread. The object was created in thread id 140030717908736 and this is thread id 140031011022656.
Can somebody know what's the problem there? I'm using django runserver in local machine, with celery and postgresql database.
Thanks!! :)
