Looking at the mitigation you've applied, I'm not sure it's correct. In particular, you're terminating the loop when you receive a NULL value, but there may actually be multiple attributes present (with no values on any of them) and you ought to continue iterating through them all.

... which is why my issue here is about the lack of documentation for the function! I tried to read up on how its supposed to work but I couldn't find any docs anywhere.
