Getting Error using NoteStore Class of Action Script 3 SDK

Hello,
I'm using Action Script 3 Software Development Kit. The getNote function of NoteStore class shows the error of 'Message Length Exceeded'.
I called on the API with the following arguments of the getNote method,
noteStore.getNote(…, …., true, false, false, false, handleGetNoteFailure, handleGetNoteSuccess).
I always get this error message:
'EDAM processing error: Message length exceeded: 256000 (type: org.apache.thrift.TApplicationError).'
This behavior remains same for any type of note, i.e. welcome note or custom note etc. I've even tried using the lower version of Flex i.e. 4.1, but in vain. There are bugs in the current version of SWC. So, I cannot use that one also.
Can anyone help me in this regard? I'll be really grateful for this.
Regards.
