execve no argument

[COOLMSF]

when I tracing ls command, execve system function has no arguments.

(base) ubuntu@ubuntu-Parallels-Virtual-Platform:~$ lurk ls | head
[23549] execve("", "", "") = 0
[23549] brk(0x0) = 0x555555579000
[23549] arch_prctl(12289, 0x7FFFFFFFE060) = -22

Is this a bug? strace do it well.
