Solve the following python programming problem given the following code:
def getFunctionForExecuteMessage(self, jsonMessage, objectToRead) : 
    if ('field' not in jsonMessage) : 
        raise MalformedMessageException ("missing 'field'") 
field = jsonMessage ['field'] 
    if (not isinstance (field, str)) : 
        raise MalformedMessageException ('fieldname was not a string') 
field = intern (field) 
    try : 
        funDef = getattr (getObjectClass (objectToRead), field) 
except : 
        raise InvalidFieldException () 
funDef = getattr (getObjectClass (objectToRead), field) 
    if (not Decorators.isFunctionToExpose (funDef)) : 
        raise InvalidFunctionException () 
if Decorators.functionExpectsCallback (funDef) : 
        if Decorators.functionExpectsExpandedArgs (jsonMessage) : 
            def caller(x, callback, arg) : 
                if isinstance (arg, list) : 
                    return getattr (x, field) (callback, * arg) 
else : 
                    return getattr (x, field) (callback, ** arg) 
return caller 
else : 
            return (lambda x, callback, * args : getattr (x, field) (callback, * args)) 
else : 
        if Decorators.functionExpectsExpandedArgs (funDef) : 
            def caller(x, callback, arg) : 
                try : 
                    if isinstance (arg, list) : 
                        callback (getattr (x, field) (* arg)) 
else : 
                        callback (getattr (x, field) (** arg)) 
except Exception as e : 
                    callback (e)

            def caller(x, callback, * args) :
