Error: /system/xbin/su: invalid uid/gid '-c'

Hi, I did everything as described, but magisk isn't patched correctly to me. From the patching logs I see this line: /system/xbin/su: invalid uid/gid '-c'

Here are the logs: $ ./patch.sh

After replacing the updated ramdisk.img inside sdk directory and rebooting device I don't see that the emulator is rooted by magisk.

Reproduced for Pixel 3 API 30, Pixel 3 API 29 (Google APis) emulators.

Any ideas how to resolve it?
