Hi Nilesh,

The issue is related to  the "Security Profile"  Which is assigned to Specific "Roles"  for the User level under the Syracuse Administration. Especially in your case The access rights for "collaborationArea" code should be select the WRITE(operation) check box.

Please see the attached screen shot.

Please choose the required operations for corresponding Authorized Codes to avoid the such a errors.
