Lesson_3/06_Adding Features to your Mashup/Solution Code/tester.py does not work

[lacki74]

I run the solution code:

1. I started Lesson_3/06_Adding Features to your Mashup/Solution Code/views.py

in another cmd I tried:
2. Lesson_3/06_Adding Features to your Mashup/Solution Code/tester.py

which leads to the following error message:
SQLite objects created in a thread can only be used in that same thread.The object was created in thread id -1245971648 and this is thread id -1256195264

can you reproduce this? is there a bug in the solution code? what I'm doing wrong?
