Please change this to an ERR_OUT_OF_RANGE error that corresponds to the bufferLength. I do not know what buffer should stand for in this case and invalid argument value errors are normally used in different contexts. Here it should definitely be an out of range error as I also suggested in my code example in my earlier comment.

'is empty and can\'t be written');
