Hi anna,
Cool project !
The foreign key mismatch in your sql table is most likely because, the key , your foreign key is referencing to , is not guaranteed to be unique.
Which means its neither the primary key , nor  having the unique constraint which is necessary for the parent key referenced in a foreign key in sqlite3.
For more info, refer to
https://www.sqlite.org/foreignkeys.html#fk_indexes
To help more, I would need to know your dbschema.
But hopefully the docs linked above, should help you solve your problem
Have a great day !
Regards,
Klien
