Does "kf.kio.core: UDSEntry for '.' not found, creating a default one. Please fix the "kioworker" KIO worker." indicate a fault in how I'm calling it?

Query

When I call the undermentioned:

#!/usr/bin/env -S sh
kioclient ls 'applications:/'

I receive the content I expect in the output, but with an unexpected error:

PS /home/RokeJulianLockhart> kioclient ls 'applications:/'
kf.kio.core: UDSEntry for '.' not found, creating a default one. Please fix the "kioworker" KIO worker.

It’s evidently minor, but I want to ensure that I’m calling it correctly.
