Warning on Arch Linux: unable to parse current version: Invalid Semantic Version

[intgr]

Describe the bug
I'm using the plumber package that is provided by Arch Linux package.

Here's the package script Arch uses to build the package: https://gitlab.archlinux.org/archlinux/packaging/packages/plumber/-/blob/main/PKGBUILD

To Reproduce
Every time I try to use the plumber write kafka command, I see following output:

> plumber read kafka --topics=x 
WARN[0000] unable to parse current version: Invalid Semantic Version 
INFO[0000] 
█▀█ █   █ █ █▀▄▀█ █▄▄ █▀▀ █▀█
█▀▀ █▄▄ █▄█ █ ▀ █ █▄█ ██▄ █▀▄ 
INFO[0000] Initializing (could take a minute or two) ...  backend=kafka

Expected behavior
It's quite confusing what this message is even trying to tell me.
