# Corner-Case Bug in GrabPERF

Just found a corner-case issue in the GrabPERF system where the charts would return an error datapoint in a graph if the server did not send an HTTP return code. However, the data tables did not see the same issue, and the data was just ignored.
Turns out that I don't factor in this empty return-code scenario in my code lookup table. Added an empty value, and voila!
Ugh!
