1336 Cannot change singleFile or unaudited attribute after instantiation
Cause
This error occurs if you attempt to change the value of the singleFile attribute of a JadeBytes object after the object is instantiated by assigning content or allocating storage; that is, after it is created and committed in a transaction, even if it is empty (no content assigned).
Action
Change the value of the singleFile attribute before you assign content or allocate storage.
