objectbox-swift: Crash on ObjectBox initialization: Duplicate index ID 1 found for property EntityD.group

Issue Basics

App crashes when we initialize ObjectBox

• ObjectBox version (are using the latest version?): 0.5.0
• Reproducibility: occurs always

Reproducing the bug

Description

I’m initializing the BoxStore on app start during the initialization of the Swinject graph.

Code

extension Store {
	static func createStore() throws -> Store {
		let directory = try FileManager.default.url(
			for: .documentDirectory,
			in: .userDomainMask,
			appropriateFor: nil,
			create: true)
		return try Store(directoryPath: directory.path)
	}
}

DBUtils

class DBUtils {
	static var sharedInstance = DBUtils()
	var store : Store!
	
	init() {
		store = try! Store.createStore()
		
		store.register(entity: EntityA.self)
		store.register(entity: EntityB.self)
		store.register(entity: EntityC.self)
		store.register(entity: EntityD.self)
	}
}

Swinject code

container.register(Store.self) { _ in
			DBUtils.sharedInstance.store }.inObjectScope(.container)

Entities

class EntityA: Entity {
	var id : Id<EntityA> = 0
	var name = ""
	var played = 0
	var won = 0
	
	var group: ToOne<EntityC> = nil

	required init() {
	}
}

class EntityB: Entity {
	var id : Id<EntityB> = 0
	var name = ""
	var matches : ToMany<EntityD, EntityB> = nil
	
	required init() {
	}
}

class EntityC: Entity {
	var id : Id<EntityC> = 0
	var name = ""
	var entitiesA: ToMany<EntityA, EntityC> = nil
	
	required init() {
	}
}

class EntityD: Entity {
	var id : Id<EntityD> = 0
    var day : Int?
	var date: Date?
	var isPlayed : Bool = false
	var localPoints: Int?
	var foreignPoints: Int?
	
	var group: ToOne<EntityC> = nil
	var fase: ToOne<EntityB> = nil
	var local: ToOne<EntityA> = nil
	var foreign: ToOne<EntityA> = nil
	
	required init() {
	}
}
