I am creating and deleting collections via Web API. While synchronizing, I'm getting the error "parent.getChildCollections is not a function".

Steps performed via API:
1. Creation of a new collection ('2024_04') and two hierarchy levels of subcollections.
2. Import of items into one of the collections of the lowest level.
3. Deletion of empty collections on the two lower levels.
