Error message, when creating fuel supply chains

Hi! After successfully running the code that adds an external scenario (bread scenario), I applied the ndb.update_all() function.

Then, after a while, I got an error message when the code was updating the fuel supply chains (I copied and pasted below what I got). I would like to know how to solve it so that I can write the database with the bread scenario. Thanks a lot!
