Even though it failed to rate one mirror, the update looks to be completed. There was just no packages to update. Remember that a warning doesn’t always equal an error.
If you mean this:
This warning can be ignored as well. Updates still will work and the core issue about the warning will probably be fixed later. Garuda is using a custom PKGBUILD on that, and there was a mention of not doing so in the future in this thread: Warning about reflector-simple when updating - #7 by dr460nf1r3
I updated just now and there was only just one package to update (vivaldi browser). Last time I updated before that was yesterday. You look to be fine.
