devkit avs call fails.

devkit avs call --signature="(uint256,string)" args='(5,"hello")'

Incorrect Usage: flag provided but not defined: -signature

2025/07/16 14:04:58 flag provided but not defined: -signature

Also the autocomplete on zsh seems broken. When I type devkit avs call --sig and press tab, I get

devkit avs call --sigpanic: runtime error: invalid memory address or nil pointer dereference
[signal SIGSEGV: segmentation violation code=0x2 addr=0x30 pc=0x10501b3b8]

Bắt đầu tại cmd/devkit/main.go, khoảng dòng 63, và tái hiện lệnh gọi avs cùng lệnh hoàn tất zsh đã được báo cáo. Theo dõi việc đăng ký lệnh avs call và đường dẫn hoàn tất được hiển thị trong stack trace của urfave/cli; hoàn tất khi tùy chọn signature được xử lý và việc nhấn tab sau --sig không còn gây panic.
