How It Affects Your App
This error indicates that a generated column cannot be used in a foreign key constraint. This means that the application cannot use the generated column to create a relationship between two tables. This can lead to data integrity issues, as the application will not be able to ensure that the data in the two tables is consistent. Additionally, the application may not be able to perform certain operations that require the generated column to be used in a foreign key constraint.
