As said in the title, i’m trying to update a OneToOne relation, but on only one side of the relation. For example :

"block": {
    "type": "title",
    "id": "d9e49507-834b-4366-afef-c673aff583cb",
    "titleBlock": {
        "title": "coucou"
    }
}

Here, Block and TitleBlock are tied by a a OneToOne relationship

If I try to update the Block entity by its id, and its related TitleBlock but without specifying its id, I get a duplicate key error.
What I suspect is happening, is : TypeORM tries to create a new TitleBlock, with the relevant blockId, before unlinking the old one. So it fails, because it would mean 2 titleBlocks with the same blockId.

Does anyone know how I can manage to handle this case, or if it is even possible ?

Thanks in advance !
