This is the 1st time i am getting an error on MB and reporting it.

The error was on
https://musicbrainz.org/artist/11844805-f486-48c2-afdd-84f4dd208f4c/alias/330473/edit
when i tried to set "Guy Wallace" as a primary alias for an artist, but may be because the main alias there was already set, it gives an error.

Internal Server Error
Oops, something went wrong!

Error:

The edit could not be created. Exception (string): Failed query:
'UPDATE artist_alias SET primary_for_locale = ? WHERE id = ?'
(1 330473)
23505 DBD::Pg::st execute failed: ERROR: duplicate key value violates unique constraint "artist_alias_idx_primary"
