Same for me and interestingly:
$ ls -ld /dev/fd/*
ls: cannot access '/dev/fd/3': No such file or directory
ls: cannot access '/dev/fd/31': No such file or directory
lrwxrwxrwx 1 eboyd53 eboyd53 0 Dec 3 10:39 /dev/fd/0 -> /dev/pty2
lrwxrwxrwx 1 eboyd53 eboyd53 0 Dec 3 10:39 /dev/fd/1 -> /dev/pty2
lrwxrwxrwx 1 eboyd53 eboyd53 0 Dec 3 10:39 /dev/fd/2 -> /dev/pty2
