YOU MEAN TO ACTUALLY FKN TELL ME IT TOOK YOU 3 DAYS TO FIGURE OUT AN "QueryFailedError: null value in column "id" violates not-null constraint" ERROR??? GTFO. These fkn "fullstack" consultants man...

Well it does sometimes take 3 days to get to the bottom of null id :) especially when you do not know corner cases of the orm. It took me ~3 days too to dig up smth fucked up about hibernate when it refused to persist nested entities' collections in subsequent inserts. Same error -- null id.
