Software version that were used:
- Spring Boot 1.5.9
The error message that triggered all the research:
2017-12-08 18:02:48.438 UTC [73] ERROR: constraint "uk_n7c2qd0x7l2yaq2xyyvs21rej" of relation "software_suite_instance" does not exist 2017-12-08 18:02:48.438 UTC [73] STATEMENT: alter table public.software_suite_instance drop constraint UK_n7c2qd0x7l2yaq2xyyvs21rej
The code fix was to properly map in both entities the link between them.
In the child entity we needed to add a field for the parent entity like:
@OneToMany @MappedBy() private ParentEntity parentEntity; // Create a getter and setter for parentEntity
The error stopped showing up after this correction.
