Cocoa error 3840

[stefanvermaas]

Hi,

Currently I'm using AFMotion, but the put request fail and I'm not quite sure why it fails. AFMotion/AFNetworking gives me the cocoa error 3840, but I don't understand why, because I'm converting everything to a JSON object.

The client is created using a shared client.

Any idea on this?

  # Update an existing model
  def update( data, remote = false )
    data_attributes = BW::JSON.generate( data.attributes )
    item = if remote
      @client.put("#{@collection}/#{data.id}", data_attributes) do |res|
        p res
        if res.success?
          res.object
        end
      end
    else
      @model.where(:id).eq(data.id).first.update_attributes(data)
    end
  end

#<AFMotion::HTTPResult:0xa4df2f0 @operation=#<AFHTTPRequestOperation:0xe1d4570> 
@object=nil 
@error=#<NSError:0xa518f40, description="The operation couldn’t be completed. (Cocoa error 3840.)", code=3840, domain="NSCocoaErrorDomain", userInfo={"NSDebugDescription"=>"JSON text did not start with array or object and option to allow fragments not set."}>>

We're currently not using the latest cocoa pods, because the latest version of cocoa pods conflicts with some other gems.

Cheers.
