Fails to fetch certain artist's works in media library view in ncmpcpp

[Ingvix]

Whenever I navigate to artist haisuinonasa, also known as ハイスイノナサ, mopidy starts shooting this error again and again until I unselect the artist.

WARNING  2022-08-04 13:41:57,155 [1594:Core-5 (_actor_loop)] mopidy.core.library
  JellyfinBackend does not implement library.search() with "exact" support. Please upgrade it.

I wonder if something breaks due to many of related titles being written in japanese and there's some character(s) it fails to handle?

Here's verbose log of the same:

I renamed some files to try to replicate this and I'm unable to make it error. The error it's spitting out is highly suspicious as well, because it's saying that the plugin doesn't support something that it absolutely supports.
