1048 Column 'category_id' cannot be null (SQL: insert into `products` (`pro_name`, `pro_code`, `stock`, `pro_pr ▶"

I have this e-commerce course on Udemy that I have been trying to follow but get the same error, I reloaded the course and even tried to clone the code but still get the same error.

This is for PHP Laravel 5.5, trying to load products to database phpmyadmin products table.

The form should load the image and product description in the database under products, nothing is loading to phpmyadmin.
