LOL - Right from the get go you have to let go of what should be vs what is when it comes to MLB scoring.
Seriously, if I had to guess, you get to the no error ruling based on an assumption by the scorer that if Javy had taken the time to stand up and set for a throw (i.e. ordinary effort play), the runner would have been safe. So by attempting the DP he went beyond ordinary effort and it's just a failed FC (and no-one got an extra base on the throw so no error was charged) even though he might have been able to take more time and go to 1st for one. Funny thing is that if had gone to 1st and made a bad throw, for certain the error would have been charged. But that's just another measure of how goofed up scoring is. And of course, the error in judgement to attempt a DP that isn't there isn't an error either. 🤷♂️
