linkResource returns Spine.SerializerError.topLevelEntryMissing

[koraykoska]

I have a profile model like that:

class Profile: Resource {
    // ...
    var followers: LinkedResourceCollection?
    var followees: LinkedResourceCollection?
    // ...

    override class var resourceType: ResourceType {
        return "profiles"
    }

    override class var fields: [Field] {
        return fieldsFromDictionary([
            // ...
            "followers": ToManyRelationship(Profile.self),
            "followees": ToManyRelationship(Profile.self)
            // ...
        ])
    }
}

Now if I have two profiles, which are already saved, and I want to link them together (so profile1 starts following profile2), I get a Spine.SerializerError.topLevelEntryMissing.

// ...

// Try to link profile2 into the followees to-many-relationship of profile1
profile1.followees?.linkResource(profile2)

SpineHelper.sharedInstance.spine.save(profile).onSuccess(callback: { (profile) in
    print("Linked...")
}).onFailure(callback: { (error) in
    print("******* ERROR *******")
    print(error)
})

The result is always the same:

ERROR serializerError(Spine.SerializerError.topLevelEntryMissing)

Am I doing something wrong? Doing self-joined relationships should be compliant with JSONAPI as well as naming to-many-relationships other than the pluralized resource name, so Spine should support this.

Can you post here the response from the server? If you enable logging Spine will output it to the console: Spine.setLogLevel(.logDebug, forDomain: .networking)

Ok I am sorry, the server responded with a wrongly rendered 500 Internal Server error and I didn't recognize it because the tests passed. This is an issue with my backend, not with Spine. Thank you for the tip.
