The request body is either missing or incomplete. Tried debugging , but it didn't specify the problem, replaced store's type from KCSAppdataStore to KCSLinkedAppdataStore, still didn't help.

Nevermind, I found reason of all my troubles, I was adding fetched entities to the NSMutableArray with addobject, Instead I should have created an array of specific type var events[Event] = [] and add entities by events.append(object)
Fixed with help of this thread https://support.kinvey.com/support/discussions/topics/5000041252. However, when I try to fetch the property
let store = KCSLinkedAppdataStore.storeWithOptions([
KCSStoreKeyCollectionName : "Events",
KCSStoreKeyCollectionTemplateClass : Event.self
])
var query:KCSQuery = KCSQuery()
store.queryWithQuery(
query,
withCompletionBlock: {
(objectsOrNil: [AnyObject]!, error: NSError!) -> Void in
if (error == nil){
var objects = objectsOrNil as [Event]
for object in objects{
EventsData.addObject(object)
}
self.TimelineData = EventsData
self.tableView.reloadData()
self.refreshControlForTimeLine.endRefreshing()
}else{
println("Error: " + error.description)
self.refreshControlForTimeLine.endRefreshing()
}
},
withProgressBlock: nil)
that's what I get

Tried everything but still can't extract image :( What I am trying to get is that Entity Event will have a property of picture ,which is extractable, but even though all the rest of 'Event' is being fetched, picture is still unavailable, still that "blob wasn't registered for your backend".

Grisha,
Can you take a look at the object in the debugger to ensure that it exists? A lot of times with relational data we will load a "stub" of the data contained in the actual object, which you can then resolve to get the actual object. Stubs generally don't have downloadURL's, and as such could give this error.

That's what happens, it shows that object was found and added to NSMutableArray but image cant be found
That's my Entity object declaration:
class Event: NSObject,KCSPersistable {
var entityId: NSString? //Kinvey entity _id
var author: KCSUser?
var name: NSString?
var details: NSString?
var picture: UIImage?
var date: NSDate?
var location: NSString?
var metadata: KCSMetadata? //Kinvey metadata, optional
override init(){
super.init()
author = KCSUser.activeUser()
}
internal override func hostToKinveyPropertyMapping() -> [NSObject : AnyObject]! {
return [
"entityId" : KCSEntityKeyId, //the required _id field
"author" : "author",
"name" : "name",
"details" : "details",
"picture" : "picture",
"date" : "date",
"location" : "location",
"metadata" : KCSEntityKeyMetadata //optional _metadata field
]
}
internal class override func kinveyPropertyToCollectionMapping() -> [NSObject : AnyObject]! {
return [
"author" : KCSUserCollectionName,
"picture": KCSFileStoreCollectionName
]
}
}

So basically I fetched the entity , and debugger told me that entity exists, even though I cant access its properties including image , it receives the imagefile id ,which I can confirm from my table management tools on website, however it still doesnt load the image itself.

Hello Grisha,
When dealing with references they need to be resolved, you will get back an id and a KinveyRef. You can check out the iOS guide for fetching relational data over here: http://devcenter.kinvey.com/ios/guides/datastore#relationaldataretrieve
