`SoundCloudTrack` Always Raises `BadArgument`

Summary

Every time I search for a song in SoundCloud with wavelink.SoundCloudTrack, it never returns anything. Rather, it raises a BadArgument exception stating that it could not find any songs matching that query.

Reproduction Steps

Run the Minimal Reproducible Code
Join a VC that your bot can join
Run the play command with your query of choice

Minimal Reproducible Code

Use the example code but replace the type annotation for the search argument from wavelink.YouTubeTrack to wavelink.SoundCloudTrack.

Expected Results

The bot would join the VC and play the song from a lavalink server's SoundCloud search with the query

Actual Results

Ignoring exception in command play:
