Hello all, i am facing problem while adding photo in kinvey. I want to add photo in people collection when user create account. Getting below error when i am trying to store photo in payslipview json serialization not supported for NSConcreteMutableData . Check out below code because i am stuck here from long time and new to programming.

[people setValue:imageData forAttribute:@"photo"];
KCSLinkedAppdataStore* store = [KCSLinkedAppdataStore storeWithCollection:[KCSCollection peopleCollection] options:nil];
[store saveObject:people withCompletionBlock:^(NSArray *objectsOrNil, NSError *errorOrNil) {
    if (errorOrNil ==  nil) {
        //was successful!
    } 
} withProgressBlock:nil];
