外键约束失败 Django 3.1.1

Question

I have a API script that uploads my term dates. For Some reason I keep getting an error that I have a FOREIGN KEY constraint failed when the script runs. Appreciate any help on how to fix this. Attached is my models and my script. None of the data will save to the table. I appreciate any help you guys can give me. Thank you so much!
