[rootlesskit:parent] error: failed to setup UID/GID map [...] failed: newuidmap: write to uid_map failed: Invalid argument

[pianotako]

I've attempted to run rootlesskit bash, but I encountered the following error message:

[rootlesskit:parent] error: failed to setup UID/GID map: newuidmap 41685 [0 1001 1 1 1001 1 2 165536 65536] failed: newuidmap: write to uid_map failed: Invalid argument

Here is the content of my /etc/subuid:

$ cat /etc/subuid
dog:1001:1
dog:165536:65536

I found that if I remove the first line of my /etc/subuid (dog:1001:1), the error does not occur.
I am curious if there is any way to keep my current configuration without causing rootlesskit bash to crash?
Any help or suggestions would be greatly appreciated.

Here it the debug message of it:
